48fa6c1280 arch/risc-v: Add missing DMB to mtimer / setmtimecmp 
The memory mapped mtimecmp lives in I/O space so must add barrier
to make sure the value sticks. Otherwise a new IRQ might fire
at once.

2670f143b5 RISC-V: Add setintstack for k210 and qemu 
This fixes CI issue, and I think the old implementation with SMP
shared 1 IRQ stack for multiple CPUs.

b0a71ce3e7 RISC-V: Remove riscv_cpuindex.c from platforms that don't need it 
riscv_mhartid is no longer called by exception_common, so can remove
this file from platforms that don't need it.

Also fixes make warning:
Makefile:123: target 'riscv_cpuindex.o' given more than once in the same rule

d5ea259828 RISC-V: Combine 3 variables that depend on CPU amount into one 
IRQ_NSTACKS, ARCH_CPU_COUNT, CONFIG_SMP_NCPUS all relate to each
other. However, a bit of clean up can be done and everything can
be merged into SMP_NCPUS.

The MPFS bootloader case works also as it requires only 1 IRQ stack
for the hart that executes as bootloader.

c6942b68d5 arch/risc-v: Add handler for misaligned load/store 
Some risc-v based chips don't support unaligned data access,
it will trigger a exception and then lead to crash.

In this patch, we handle the misaligned access by software to make
system run continue.

d38b4965f8 MPFS: Prepare support for S-mode 
- Access to PLIC via S-mode registers
- Access to IRQs via S-mode registers / definitions
- Initialize S-mode registers upon boot
- Initialize per CPU area before nx_start

NOTE: S-mode requires a companion SW (SBI) which is not yet implemented,
thus S-mode is not usable as is, yet.

71ced1f1a9 RISC-V: Implement skeleton for a per CPU structure 
It might be useful to store things in memory per CPU. The tricky part
is that all CPUs run the same code and see the same memory, so some
kind of centralized access is required.

For now, the structure contains the hart id.

Access to the structure elements is provided via sscratch, which is
unique for every hart!
