arm/mm: Backport of 3159f372354e8e1f5dee714663d70

ARM: 7840/1: LPAE: don't reject mapping /dev/mem above 4GB

With LPAE enabled, physical address space is larger than 4GB. Allow mapping any
part of it via /dev/mem by using PHYS_MASK to determine valid range.

PHYS_MASK covers 40 bits with LPAE enabled and 32 bits otherwise.

arch/arm/mach-axxia: Work-Around for Event Problems in v1.0 Silicon

SEV/WFE are unusable in v1.0 silicon.  The boot loader now sets bit 7
in the ACLTR register of each core, making wfe a nop.  At present,
bit 7 of the ACTLR does not work in simulation and emulaton.  Until
that is corrected, this work-around is necessary.
