needed anymore.
Decouple the IRAM heap from the text allocator since that heap can
still be used as a generic pool of memory.
Implement the up_extraheaps_init function to initialize all of the
additional heaps.

Write protection must be disabled before performing changes to the WDT
registers. Furthermore, the routine was resetting the wrong field from
the RTC WDT register.
The RTC_CNTL_WDT_FLASHBOOT_MOD_EN field relates to Flash Boot Protection
and it is enabled by the 1st stage bootloader. The 2nd stage bootloader
takes care of disabling it.
Then the 2nd stage bootloader enables the RTC WDT for checking the
startup sequence of the application image.

This memory region can be accessed by both I & D buses, so the heap can
be used for data storage and code execution.

Summary:
- I noticed that the getcoreid macro in the latest esp-idf
is much simpler than the current NuttX's.
- This commit replaces the macro with the latest esp-idf's
Impact:
- SMP only
Testing:
- Tested with esp32-devkitc:wapi_smp

instead calling kmm_heapmember or umm_heapmember because:
1.The stack supplied by caller may allocate from heap too
2.It's hard to implement these two function in ASan case

Summary:
- According to the Xtensa ISA document, this ISYNC instruction
between WSR SCOMPARE1 and S32C1I is unnecessary
Impact:
- SMP only

Summary:
- I noticed that DEBUGASSERT sometimes happens in nxsem_wait()
when testing Wi-Fi with esp32-devkitc:wsifi_smp
- The call stack was not from an interrupt handler and actually
g_current_regs[] were correct, even though asserted with
(up_interrupt_handler() == false)
- Finally, I found that we need to call rsync after we set
a new value to the PS register which is described in the
Xtensa document.
- This commit fixes this issue
Impact:
- All xtensa architectures
Testing:
- Tested with esp32-devkitc:wifi_smp and esp32-devkitc:wifi

All modern desgin support stack pointer and it's also an
important information, so let's standardize this interface.
