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.
