arch-arm: Fix secure write of SCTLR when EL3 is AArch64
MiscRegisters are not banked between secure and non-secure mode if EL3
is not implemented or if EL3 is using AArch64 (highestELIs64). In this
scenario a unique register is used and it is mapped to the NS version
(see snsBankedIndex implementation), so that a secure world read/write
should access the non secure storage.
