The Simple Boot feature for Espressif chips is a method of booting
that doesn't depend on a 2nd stage bootloader. Its not the
intention to replace a 2nd stage bootloader such as MCUboot and
ESP-IDF bootloader, but to have a minimal and straight-forward way
of booting, and also simplify the building.
This commit also removes deprecated code and makes this bootloader
configuration as default for esp32 targets and removes the need
for running 'make bootloader' command for it.

This current driver does not handle well netpkts used in the
write buffers.
I learned about this document:
https://github.com/apache/nuttx/blob/master/Documentation/components/net/netdriver.rst
After I ported and contributed the original driver.
However from the document, I understand these types of drivers are
simpler to implement and I could simplify the driver and handle
correctly the TCP write buffers.
- This PR adds the LED Driver for Ox64 Board (User LEDs and Auto LEDs)
- Ox64 LED Driver will be used by the Rust Blinky App for Google Summer of Code
- User LED 1 is configured for GPIO 29. Other User LEDs and Auto LEDs shall be configured by the NuttX Dev.
- The code is derived from NuttX PinePhone LED Driver
Add addrenv support for x86_64.
For now we support mapping on PT level, so PD, PDT and PML4 are static

Only in the non-critical region， nuttx can the respond to the irq and not hold the lock
When returning from the irq, there is no need to check whether the lock needs to be restored

When the PSRAM is enabled, we should not allocate the TX/RX
buffers there, so we use kmm_calloc here, to make it into IRAM,
so the ethernet controller can read bytes from it.
