ARM: SAMSUNG: Consolidate uncompress subroutine
For mach-exynos, uart_base is a pointer and the value is calculated in the machine folder. For other machines, uart_base is defined as a macro in platform directory. For symmetry, the uart_base macro definition is removed and the uart_base calculation is moved to specific machine folders. This would help us consolidating uncompress subroutine for s5p64x0.
