This PR adds support for PINE64 Star64 64-bit RISC-V SBC, based on StarFive JH7110 SoC. Most of the code is derived from NuttX for QEMU RISC-V (Kernel Mode). [The source files are explained in the articles here](https://github.com/lupyuen/nuttx-star64)
Modified Files:
boards/Kconfig: Added Star64 board
New Files in boards/risc-v/jh7110/star64:

platforms/risc-v/jh7110/boards/star64/index.rst: Building and booting NuttX for Star64
Add documentation referring to sim:alsa defconfig, about how to
mount host system files in the simulator using `hostfs` and
playing them using the ALSA adapter.

* Documentation/guides/zerolatencyinterrupts.rst:
Add paragraph that defines jitter. Fix a few minor typos. Fix
incorrect reStructuredText formatting for bulletpoints (they were
being rendered like 2nd level bulletpoints).

- NewReno congestion control algorithm is used to solve the problem
of network congestion breakdown. NewReno congestion control includes
slow start, collision avoidance, fast retransmission, and fast
recovery. The implementation refers to RFC6582 and RFC5681.
- In addition, we optimize the congestion algorithm. In the conflict
avoidance stage, the maximum congestion window max_cwnd is used to
limit the excessive growth of cwnd and prevent network jitter
caused by congestion. Maximum congestion window max_cwnd is updated
with the current congestion window cwnd and the update weight is
0.875 when an RTO timeout occurs.

This implements the changes required to genreate the pdf version
of the documentation. The pdf will be generated as a build artifact
attached to the build. This is the first patch to enable this
a follow on patch to the website repo will publish the pdf to the
NuttX website.
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`
Adds support for the ES8311 codec on the ESP32-S2-Kaluga-1 board. This commit also adds basic configurations for testing and updates the board documentation.
Added examples of using the RTP Tools (`rtpdump`, in particular)
to receive RTP packets and 1) print the data and/or 2) playback
audio content through I2S.
