[PATCH] ARM: EXYNOS: Add missing static to file-scope declarations

[Krzysztof Kozlowski]

The 'pm_data', 'exynos_release_ret_regs' and
'exynos5420_release_ret_regs' are not exported nor used outside of
suspend.c file. Make them static.

This fixes following sparse warnings:
arch/arm/mach-exynos/suspend.c:83:23: warning: symbol 'pm_data' was not declared. Should it be static?
arch/arm/mach-exynos/suspend.c:106:14: warning: symbol 'exynos_release_ret_regs' was not declared. Should it be static?
arch/arm/mach-exynos/suspend.c:117:14: warning: symbol 'exynos5420_release_ret_regs' was not declared. Should it be static?
