ANDROID: KVM: arm64: s2mpu: Extract L1ENTRY_* consts

Browse Source 
Extract the L1ENTRY_ATTR_{PRON,GRAN}_MASK constants out of macros that
create the corresponding constants. This will allow EL1 users to use the
masks to get the fields out of register values. Also extract
L1ENTRY_L2TABLE_ADDR_SHIFT for adjusting the L2 table address.
