Some cases need multiple nop instructions and arm64 already has a

use a helper to add n nops.

So add a similar thing to riscv and convert the T-Head PMA
alternative to use it.

riscv: introduce nops and __nops macros for NOP sequences
riscv: convert the t-head pbmt errata to use the __nops macro

Thanks, these are on for-next. I had to fix up some minor conflicts, but
hopefuly nothing went wrong.
