ARM: S5P: Remove fixed uart offset dependent code
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.
