Add chip GD32F450 of GD32MCU
This patch adds new chip family, stm32wl5x. This is bare minimum
implementation of said chip. I've tested this by running nsh.
There are only two chips in this family, stm32wl55 and stm32wl54.
The only difference between them is that stm32wl55 has LORA.
stm32wl5 is dual CPU (not core!). Right now only CPU1 is implemented.
CPU0 has access to radio hardware (while CPU1 does not). Chip is
designed so that CPU0 handles radio traffic while CPU1 does the
heavy lifting with data - there is communication pipe between two
CPUs.
I plan to use nuttx on CPU1 and LORA from stm32cube on CPU0 so I
don't have implementing CPU0 right now - once we have working LORA
in nuttx this may change.
Peripherals (except for radio) are shared so it's best to focus on
CPU1 to initialize all peripherals so that CPU0 can only use them
later. There is no real benefit to implement CPU0 if we don't have
working LORA/radio support in nuttx.
In time I will be implementing more and more things from this chip.
Right now I would like this minimal implementation to be merged in
case someone wants to work on this chip as well.

patch v1->v2
- fixed formatting (suggested by Alan Carvalho de Assis)
- rebased patch to master (previous patch was based on nuttx-10.2
and did not compile on master)

arm/armv7-[a|r]: move fpu save/restore to assembly handler
Save/Restore FPU registers in C environment is dangerous practive,
which cannot guarantee the compiler won't generate the assembly code
with float point registers, especially in interrupt handling

The current context save implementation saves registers of each task
to xcp context, which is unnecessary because most of the arm registers are
already saved in the task stack, this commit replace the xcp context with
stack context to improve context switching performance and reduce the tcb
space occupation of tcb instance.

After check the official specification of ARM ISA
and Thumb ISA, the arch_setjmp_thumb.S are written
by arm unified assembly language,
so it easy to make it works for ARM and thumb ISA.

Architecture support for STMicroelectronics STMU585xx MCUs. This is
based on corresponding code for STM32L5, but has been considerably
adjusted. Tested with a B-U585I-IOT02A board and a simple NSH
configuration, but only running NuttX in the non-secure world with
TrustedFirmware-M.

This commit adds new files that support functionality of QSPI driver in
SPI Master Mode. This functionality is included in new files sam_qspi_spi.x
to avoid too much mess in the source code. QSPI in SPI mode can be turn
on by config option SAMV7_QSPI_SPI_MODE.

Rearchitect video driver:
- Define two video I/F(struct imgsensor_ops_s and struct imgdata_ops_s),
and support them.
- CISIF driver supports new video I/F struct imgdata_ops_s.
- ISX012 driver supports new video I/F struct imgsensor_ops_s.
- Move ISX012 driver to general driver directory.
In AArch32, the frame pointer is stored in register R11 for ARM code or register R7 for Thumb code.
In AArch64, the frame pointer is stored in register X29.
