arm64: Add function for reading TCR register at current EL
TCR at EL1 is 64-bit whereas at EL2 and EL3 it is 32-bit. Thus, use 64-bit
variables to read / write TCR at current EL. raw_read_tcr_elx will handle it
automatically by accepting / returning 32-bit / 64-bit values.
BUG=chrome-os-partner:33962
