target/arm: allow setting SCR_EL3.EnTP2 when FEAT_SME is implemented
Updates write_scr() to allow setting SCR_EL3.EnTP2 when FEAT_SME is
implemented. SCR_EL3 being a 64-bit register, valid_mask is changed
to uint64_t and the SCR_* constants in target/arm/cpu.h are extended
to 64-bit so that masking and bitwise not (~) behave as expected.
This enables booting Linux with Trusted Firmware-A at EL3 with
"-M virt,secure=on -cpu max".
