lib: utils: Make the enforce permission bit configurable from DT
The domain_support.md documentation states that the enforce permission
bit (BIT[6]) could be set in the "regions" property of a domain
instance DT node. However, this bit is masked in the current
implementation. This patch unmasks the bit to make it configurable
from DT.
