When calling '_reset_regs', it'll reset all registers except some
specific registers (ra, a0, a1, and a2).
Both boot HART and non-boot HARTs will execute the '_start_warm'
function. Therefore, when '_reset_regs' is called in '_start_warm', it
will reset all registers except some specific registers (ra, a0, a1 and
a2) for both boot HART and non-boot HARTs.
