IRAM0/DRAM0 addr range update, on s3, c3, c2, h4, c6:
IRAM0_ADDRESS_LOW ~ IRAM0_ADDRESS_HIGH
DRAM0_ADDRESS_LOW ~ DRAM0_ADDRESS_HIGH
now are for the real IRAM0 and DRAM0
This commit gives basic mmu driver framework. Now it is able to maintain
mmu virtual address usage on esp32, esp32s2 and esp32s3. Usage to
external virtual address should rely on mmu functions to know which
address range is available, instead of hardcoded.
This commit also improves psram memory that is added to the heap
allocator. Now it's added to the heap, according to the memory
alignment.
