RealView: Move the UART definitions to EB specific files
Since the PB1176 has different UART base addresses, this patch moves the definitions form platorm.h to board-eb.h. It also modifies uncompress.h to detect the platform type at run-time. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
