lib: sbi: Add hart_ prefix to PMP functions

Browse Source 
PMP functions that deal with hart PMP CSRs are given a sbi_hart_ prefix,
to distinguish from RISC-V PMP encoding functions.

The is_pmp_entry_mapped() function is changed a little more, to align
with other PMP conventions, and made to return a bool to make it more
obvious that it returns a bool and not an SBI_ return code.
