Furquan Shaikh 9c8cfc5c25 coreboot arm64: Add proper masks for setting SCTLR and SCR regs to 0 at init 
Since RES1 and RES0 bits are marked as SBOP(Should-Be-One-or-Preserved) and
SBZP(Should-Be-Zero-or-Preserved) respectively, resetting the SCTLR and SCR
registers should be done with proper bitmask.

BUG=None
BRANCH=None
TEST=Compiles successfully and verified that the RES bits are preserved across
register writes.
