Nicolas Pitre 147728775f riscv: pmp: properly initialize per-thread m-mode/u-mode entry array 
Retrieve the pmpaddr value matching the last global PMP slot and add it
to the per-thread m-mode and u-mode entry array. Even if that value is
not written out again on thread context switch, that value can still be
used by set_pmp_entry() to attempt a single-slot TOR mapping with it.

Nicely abstract this with the new z_riscv_pmp_thread_init() where the
PMP_M_MODE(thread) and PMP_U_MODE(thread) argument generators can be
used.
