This commit enables using ESP32-P4's PSRAM on Function-EV-Board.
The in-chip PSRAM memory is added to the user heap and the internal
memory is dedicated to a kernel heap.

On ESP32-P4 rev < v3, the 768KB HP L2MEM is split into two
non-contiguous regions: sram_low and sram_high. Previously only
sram_low was used for the heap, wasting 384KB of sram_high.
Export _sram_high_heap_start and _sram_high_heap_end symbols from
the linker script and add sram_high to the heap via kumm_addregion()
in riscv_addregion() when MM_REGIONS > 1.
