370152f3ba RISC-V: Move mhartid to own assembly macro+function
Hartid and cpuindex are not the same thing. Hartid is needed regardless
of SMP, for external interrupt handling etc.

SMP needs cpuindex which might not be index == hartid, so both are
needed. IMO it is clearer to provide separate API for both.

Currently the implementation of up_cpu_index is done a bit lazily,
because it assumes hartid == cpu index, but this is not 100% accurate,
so it is still missing some logic.

ff210e1c2d arch/stack_color: correct the end address of stack color
The different optimization of compilers will cause ambiguity in
obtaining sp through up_getsp() in arm_stack_color(), if compile
with clang and enable the optimization flag (-Ofast), up_getsp()
call will be earlier than push {r0-r9,lr}, the end address of color
stack will overlap with saved registers.
