The original assumption was that the interrupt numbers are divided
so that 16 pins from 1 port are handled by a single interrupt source.
So source 0 would handle pins 0-15 and source 1 would handle pins 16-31.
This assumption is wrong, each pin has two sources, thus there are two
interrupt lines for each pin.
The driver uses source 0, and leaves source 1 disabled.
According to the qemu source code, hw/arm/virt.c.
The secure memory of the ARM Virt board is [0xe000000~0xf000000]
and the non-secure memory is configured as [0x40000000~0xffffffff].
We made the following adjustments based on the above virt board configuration

Using CSR name depends on compiler support heavily, but CSR
encoding does not have this problem. It also make it easy to
add new CSR support even if the compiler does not support.
Unify CSR access by using the CSR encoding macro.

This patch adds more debug related CSR definitions
to arch/risc-v/include/csr.h.
These definitions are from the RISC-V Debug Specification
Version 1.0 rc1 (https://github.com/riscv/riscv-debug-spec).

Extracting global variable information using scripts:
kasan_global.py:
1. Extract the global variable information provided by the -- param asan globals=1 option
2. Generate shadow regions for global variable out of bounds detection
Makefile:
1. Implement multiple links, embed the shadow area into the program, and call it by the Kasan module

RTC data was not being correctly placed on RTC's memory data due to
linker issues. Also, the image's RTC memory segment was not being
properly parsed by the bootloader.
This is a high resolution PWM driver, utilizing one 16-bit Flex-IO timer for
generating PWM period and the rest of the timers to generate PWM duty cycles.
This means that the period has to be the same for every PWM generated from one
FLEXIO block, but this way we can get 16-bit resolution for the PWM signals.
For a typical IMX9 HW there are 8 timers for each Flex-IO block, which means
that by using this driver one can get 7 PWM outputs from one block.
This driver can be later extended to have configuration options to use all
8 channels per flex-io by either using 8+8 -bit timer (less resolution) or by
using an external trigger from an LPIT.

This commit implements the common RMT driver (already available for
the other Espressif's xtensa-based devices) for ESP32.
This allows us to have a proper separation between the lower and
upper-half drivers and use the 'ws2812' example to drive WS2812 RGB
LEDs.

This commit just rearranges the order of the types, data and
functions without modifying them. This is done to make it look more
similar with ESP32's ble adapter and ease maintanence.
