Currently NuttX on Arm64 supports Generic Interrupt Controller (GIC) Versions 3 and 4: [`arm64_gicv3.c`](https://github.com/apache/incubator-nuttx/blob/master/arch/arm64/src/common/arm64_gicv3.c), [`arm64_gic.h`](https://github.com/apache/incubator-nuttx/blob/master/arch/arm64/src/common/arm64_gic.h). This PR adds support for GIC Version 2, which is needed by [Pine64 PinePhone](https://lupyuen.github.io/articles/interrupt) based on Allwinner A64 SoC.
This 64-bit implementation of GIC v2 is mostly identical to the existing GIC v2 for 32-bit Armv7-A ([`armv7-a/arm_gicv2.c`](https://github.com/apache/incubator-nuttx/blob/master/arch/arm/src/armv7-a/arm_gicv2.c), [`armv7-a/gic.h`](https://github.com/apache/incubator-nuttx/blob/master/arch/arm/src/armv7-a/gic.h)), with minor modifications to support 64-bit Registers (Interrupt Context).
- `arch/arm64/Kconfig`: Under "ARM64 Options", we added an integer option `ARM_GIC_VERSION` ("GIC version") that selects the GIC Version. Valid values are 2, 3 and 4, default is 3.
- `arch/arm64/src/common/arm64_gicv2.c`: Implements 64-bit GIC v2 based on 32-bit [`armv7-a/arm_gicv2.c`](https://github.com/apache/incubator-nuttx/blob/master/arch/arm/src/armv7-a/arm_gicv2.c) and [`armv7-a/gic.h`](https://github.com/apache/incubator-nuttx/blob/master/arch/arm/src/armv7-a/gic.h), modified to support 64-bit Registers (Interrupt Context).
Function and Macro Names have not been changed, for easier cross-referencing between the 32-bit and 64-bit implementations of GIC v2.
- `arch/arm64/src/common/arm64_gicv3.c`: Added Conditional Compilation for GIC v3. This file will not be compiled if `ARM_GIC_VERSION` is 2.
- `arch/arm64/src/common/arm64_gic.h`: Added the Version Identifier for GIC v2. At startup we read the GIC Version from hardware and verify that it matches `ARM_GIC_VERSION`.
- `arch/arm64/include/qemu/chip.h`: Added the QEMU Base Addresses for GIC v2.
- `arch/arm64/src/common/Make.defs`: Added the source file that implements GIC v2.
- `boards/arm64/qemu/qemu-armv8a/README.txt`: Added the documentation for testing GIC v2 with QEMU.
- `boards/arm64/qemu/qemu-armv8a/configs/nsh_gicv2/defconfig`: Added the Board Configuration `qemu-armv8a:nsh_gicv2` for testing GIC v2 with QEMU. Identical to `qemu-armv8a:nsh`, except that `ARM_GIC_VERSION` is 2.
- Add ioctl method to enable allocating the apb buffer.
- Add RX methods to set data width, sample rate, channels and
for receiving data from the I2S peripheral.
- Update the i2schar defconfig to enable the I2S receiver.
- Add nxlooper defconfig to enable testing the RX interface.
- Add specific bindings on ESP32 bringup to enable nxlooper
to work without the need of any specific codec.

In the past, header file paths were generated by the incdir command
Now they are generated by concatenating environment variables
In this way, when executing makefile, no shell command will be executed,
it will improve the speed of executing makfile

Currently the IHC (Inter Hart Communication) depends on OpenAMP and
rptun. However, the bootloader portion of the IHC doesn't need
either of them. Now they are wasting a lot of bootloader space.
Reorganize the bootloader portion into a separate file 'mpfs_ihc_sbi.c'.
This file contains the OpenSBI vendor extensions, or the only required
functionalities for the bootloader. On the other hand, 'mpfs_ihc.c'
contains the non-bootloader code.
This patch also makes it possible to utilize 2 RPMSG channels. This
has been tested so that 2 separate NuttXs on harts 1 and 2 communicate
with Linux kernel that runs on harts 3 and 4.
New configuration files are added as well:
- rpmsg-ch1: sample config for RPMSG
- rpmsg-ch2: sample config for another RPMSG channel
- rpmsg-sbi: sample bootloader config for RPMSG/OpenSBI
