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.
Most of the functions used to set the peripherals are available for
all Espressif's chips. This commit uses this set of functions and
remove outdated functions that perform the same operations in a
chip level.
This commit updates the Wi-Fi and the BLE driver of ESP32. Most of
the changes rely on using the common sources and header files for
xtensa-based Espressif's SoCs.
The new Wi-Fi driver supports WPA3-SAE for both Station and SoftAP
mode. BLE's coexistence mode was enhanced according to the latest
libraries.
Please note that other sources required minor changes in order to
be compatible with the common sources.
Whenever a SPI flash operation will take place, it's necessary to
disable the cache and run no code from the flash. This includes
pausing the other CPU (when `CONFIG_SMP=y`). This commit prevents
an error to occur when the CPU core is evaluated before the task
is increased to the max priority.

Avoid using static mutex and recursive mutex as the resource to be
acquired/release. Instead, create a specific lock for each call if
it does not exist.

This driver is used with QEMU, to make it possible
to use networking.
This is not the MAC in ESP32, however, it can be used with QEMU.
The code was shamelessly copied from 31dac92e5f
cpu0 thread0: cpu1:
sched_yield()
nxsched_set_priority()
nxsched_running_setpriority()
nxsched_reprioritize_rtr()
nxsched_add_readytorun()
up_cpu_pause()
IRQ enter
arm64_pause_handler()
enter_critical_section() begin
up_cpu_paused() pick thread0
arm64_restorestate() set thread0 tcb->xcp.regs to CURRENT_REGS
up_switch_context()
thread0 -> thread1
arm64_syscall()
case SYS_switch_context
change thread0 tcb->xcp.regs
restore_critical_section()
enter_critical_section() done
leave_critical_section()
IRQ leave with restore CURRENT_REGS
ERROR !!!
Reason:
As descript above, cpu0 swith task: thread0 -> thread1, and the
syscall() execute slowly, this time cpu1 pick thread0 to run at
up_cpu_paused(). Then cpu0 syscall execute, cpu1 IRQ leave error.
Resolve:
Move arm64_restorestate() after enter_critical_section() done

WS2812 data is encoded into RMT items according to the RMT clock
source. This commit makes it by using the actual clock source in
spite of a pre-defind value.
Enable with ./tools/configure.sh -l esp32-devkitc:dac
DAC channel 0 = GPIO 25
DAC channel 1 = GPIO 26
default path: /dev/dac0
Resolution 8 bits = values 0~255
Voltage: 0~Vref
The reference voltage 'Vref' here is input from the pin VDD3P3_RTC
which ideally equals to the power supply VDD (3.3V).

ESP32 is supported on NuttX starting from chip revision 3.0. This,
however, didn't prevent the user from using older chip revisions,
which caused unexpected behaviors. This commit checks chip revision
before finishing booting NuttX.
This commit is intended to update the EFUSE's register content and
update related configs:
- Remove duplicated configs from `esp32_soc.h`;
- Add missing header files from APB registers;
- Add missing macro definitions from EFUSE;
- Update related code to use the new macros;
