lib: sbi: fix number of PMP entries detection
CSR_PMPADDRn lower bits may read all-0 or all-1, depending on
the configuration. For TOR it is all-0, for NAPOT - all-1.
Thus if PMP entry was pre-configured as NAPOT, original code would
stop scanning because value read back not equal to the written one.
Mask lower bits before comparison to fix this
