ARM: EXYNOS: Use wfi macro in platform_do_lowpower
As per commit b3377d186572 ("ARM: 7064/1: vexpress: Use wfi macro
in platform_do_lowpower."), wfi macro should be used instead
of the hardcoded WFI instruction.
This fixes following oops with a kernel compiled in Thumb-2 mode.
$ reboot
reboot
Disabling non-boot CPUs ...
IRQ153 no longer affine to CPU1
CPU1: shutdown
Internal error: Oops - undefined instruction: 0 [#1] PREEMPT SMP THUMB2
Modules linked in:
CPU: 1 Not tainted (3.9.0-rc1-00015-gce76372 #1)
PC is at 0xc065858e
LR is at exynos_cpu_die+0x53/0xc0
Tested on EXYNOS5250 based Arndale board.
