lib: sbi: Fix PMP CSR detection
HiFive unleashed currently implements fewer than 56 bits of physical
address so existing PMP CSR detection is broken.
PMP address register encodes bits 55-2 of a 56-bit physical address,
Not all physical address bits may be implemented, So just check
minimum 1 bit.
Fixes: 74d1db706293 ("lib: sbi: Improve PMP CSR detection and
progamming")
