ARM: S5P: Remove fixed uart offset dependent code

Browse source 
The uart offset between channels has been 0x400 for all S5P series
and to present virtual and physical offsets, both number 0x400 and
S3C_UART_OFFSET have been used together.
This patch removes the use of the number 0x400 and expands the virtual
mapping size of S3C_VA_UART from 4KB to 512KB to support the CPU with
S3C_UART_OFFSET being 0x10000.
