[PATCH 1/4] ARM: EXYNOS: Fix definitions of S5P_ARM_CORE_* registers

[Tomasz Figa]

On SoCs with more than 2 cores there are more than 2 S5P_ARM_CORE_*
registers that can be addressed with fixed stride of 0x80. This patch
renames the definitions of S5P_ARM_CORE1_* registers to be S5P_ARM_CORE_*
and make them take physical core ID as argument to calculate register
address.
