[PATCH] ARM: Exynos : Fix build error with thumb2

[Santosh Shukla]

From: santosh shukla <santosh.shukla at linaro.org>

Add non-global symbol .LLl2x0_regs_phys to avoid build break in thumb2 mode.

IIUC, arm assembler fail to load value of "global" variable
l2xo_regs_phys for thum2 mode and wrapping it in non-global symbol like
.Ll2x0_regs_phys solves the build break issue.

arch/arm/mach-exynos/sleep.S: Assembler messages:
arch/arm/mach-exynos/sleep.S:57: Error: invalid immediate for address
calculation (value = 0x00000004)

fix inspired from [1]
