f5cdfa73dc risc-v/mpfs: clear L2 before use
SiFive document: "ECC Error Handling Guide" states:

"Any SRAM block or cache memory containing ECC functionality needs to be
initialized prior to use. ECC will correct defective bits based on memory
contents, so if memory is not first initialized to a known state, then ECC
will not operate as expected. It is recommended to use a DMA, if available,
to write the entire SRAM or cache to zeros prior to enabling ECC reporting.
If no DMA is present, use store instructions issued from the processor."

Clean the cache at this early stage so no ECC errors will be flooding later.

4ec7af779d nuttx/boards:init_array.* needs to be executed in order
When I try to set priorities in certain programs, such as init_priority(HIGH_PRIORITY), I've noticed that during linking, there's no guarantee that the programs will be compiled in the sequence I've specified based on priority. This has led to some runtime errors in my program.

I realized that in the ld file, when initializing dynamic arrays, there's no assurance of initializing init_array.* before init_array. This has resulted in runtime errors in the program. Consequently, I've rearranged the init_array.* in the ld file of NuttX to be placed before init_array and added a SORT operation to init_array.* to ensure accurate initialization based on priorities during linking.

fc3167b584 boards/riscv/mpfs: Remove reference to .vectors in linker scripts
There is no such section. Instead, place the object mpfs_head.o at the start of
the text.

Put mpfs_head.o directly into the arch library; there is no need to define
it separately in HEAD_ASRC.
