ARM: 6517/1: kexec: Add missing memory clobber to inline asm in crash_setup_regs()
Currently, the inline asm is passed &newregs->ARM_r0 as in input,
when modifying multiple fields of newregs.
It's plausible to assume that GCC will assume newregs->ARM_r0 is
modified when passed the address, but unfortunately this assumption
is incorrect.
Also, GCC has no way to guess that the other ARM_r* fields are
modified without the addition of a "memory" clobber.
