Yu-Chien Peter Lin 90c3b94094 lib: sbi_domain: print unsupported SmePMP permissions ...

The reg->flag is encoded with 6 bits to specify RWX
permissions for M-mode and S-/U-mode. However, only
16 of the possible encodings are valid on SmePMP.

Add a warning message when an unsupported permission
encoding is detected.
