Usually the startup script is placed under /etc. The contents of the etc directory
are compiled and linked with Nuttx binary in the form of romfs. After startup,
it will be mounted by Nsh.
etc is generated by the different boards, that use genromfs and xxd tools to generate
and compile it into the Nuttx, for example: boards/arm/at32/at32f437-mini/tool/mkromfs.sh
The more common method is etc image generated from the content in the corresponding
board/arch/board/board/src/etc directory, and added by Makefile for example:
boards/sim/sim/sim/src/etc.
But in kernel/protected mode, Nuttx kernel and apps are run in different privileged/
non-privileged mode or the isolated binarys, so as that nsh should use syscall to
access Nuttx kernel by exported API. In this scenario, nsh can not mount the etc image
content, because that is generated in board and as a part of Nuttx kernel.
changes:
- move etc romfs mount from nsh to Nuttx, but keep the script to parse and execute.
- move and rename the related CONFIG, move customized nsh_romfsimg.h to etc_romfs.c
in boards, and no need declaration for romfs_img/romfs_img_len.
This commit changes and updates all configurations in Nuttx arch/board as much as possible,
but if any missing, please refer to the following simple guide:
- rename CONFIG_NSH_ROMFSETC to CONFIG_ETC_ROMFS, and delete CONFIG_NSH_ARCHROMFS in defconfig
- rename the etc romfs mount configs, for example CONFIG_NSH_FATDEVNO to CONFIG_ETC_FATDEVNO
- move customized nsh_romfsimg.h to etc_romfs.c in board/arch/board/board/src and no need
declaration for romfs_img/romfs_img_len.
- delete default nsh_romfsimg.h, if ROMFSETC is enabled, should generate and compile etc_romfs.c
in board/arch/board/board/src.

Currently only Port UART0 is supported for Allwinner A64. This PR adds support for all UART Ports: UART1 to UART4. (Except R-UART, which is a special low-power UART)
This is required for the upcoming LTE Modem Driver (Quectel EG25-G) for PINE64 PinePhone, which uses UART3. [(Details here)](https://lupyuen.github.io/articles/lte2)
The code was adapted from the NuttX UART Driver for Allwinner A1X: [`a1x_serial.c`](https://github.com/apache/nuttx/blob/master/arch/arm/src/a1x/a1x_serial.c)
`arch/arm64/src/a64/a64_serial.c`: Added ports UART1 to UART4, based on [`a1x_serial.c`](https://github.com/apache/nuttx/blob/master/arch/arm/src/a1x/a1x_serial.c)
`arch/arm64/src/a64/a64_serial.h`: Added IRQs for UART1 to UART4. Moved UART Base Addresses to `a64_memorymap.h`
`arch/arm64/src/a64/hardware/a64_memorymap.h`: Added UART Base Addresses for UART0 to UART4
`arch/arm64/src/a64/Kconfig`: Added UART1 to UART4 to Allwinner A64 Peripheral Selection menu
`boards/arm64/a64/pinephone/configs/lcd/defconfig`, `lvgl/defconfig`, `nsh/defconfig`, `sensor/defconfig`: Fixed `UART1_SERIAL_CONSOLE` to `UART0_SERIAL_CONSOLE`
Summary
For ARM64 architecture, the arch timer is 64-bit,
the CONFIG_SYSTEM_TIME64 need to be enabled just like
x86_64 and risc-v 64

This PR adds the driver for Xingbangda XBD599 LCD Panel (based on Sitronix ST7703 LCD Controller) on PINE64 PinePhone. This PR also includes:
- The driver for X-Powers AXP803 Power Mgmt IC, which calls our driver for Allwinner A64's Reduced Serial Bus. The PMIC Driver is needed to power on the MIPI DSI Interface for the LCD Panel.
- A simple Display Driver that renders a Test Pattern on the LCD Display at startup. It calls our Allwinner A64 drivers for Display Engine, Timing Controller TCON0 and MIPI Display Serial Interface.
The NuttX Frame Buffer Driver will be implemented in the next PR.
`arch/arm64/src/a64/a64_de.c`, `a64_de.h`: Changed the Frame Buffer pointer to `const` for Allwinner A64 Display Engine
`arch/arm64/src/a64/hardware/a64_memorymap.h`: Added the Base Address for PWM, for controlling the PWM Backlight
`boards/arm64/a64/pinephone/src/pinephone_bringup.c`: Call `fb_register()` to start the Display Driver at startup
`boards/arm64/a64/pinephone/src/Makefile`: Added LCD Driver, PMIC Driver and Display Driver to Makefile
`boards/arm64/a64/pinephone/Kconfig`: Added the Kconfig option for "PINE64 PinePhone > LCD Display" (`CONFIG_PINEPHONE_LCD`) which enables the LCD Driver, PMIC Driver and Display Driver
`boards/arm64/a64/pinephone/src/pinephone_lcd.c`, `pinephone_lcd.h`: Driver for Xingbangda XBD599 LCD Panel
`boards/arm64/a64/pinephone/src/pinephone_pmic.c`, `pinephone_pmic.h`: Driver for X-Powers AXP803 Power Mgmt IC
`boards/arm64/a64/pinephone/src/pinephone_display.c`: Simple Display Driver that renders a Test Pattern in `up_fbinitialize()`
`boards/arm64/a64/pinephone/configs/lcd/defconfig`: New PinePhone Board Configuration `pinephone:lcd` that enables the LCD Driver (`CONFIG_PINEPHONE_LCD`)
`platforms/arm/a64/boards/pinephone/index.rst`: Added PinePhone Board Configuration `pinephone:lcd` that enables the LCD Driver
