ARM: OMAP: Split plat/serial.h for omap1 and omap2+
For omap1, we'll keep mach/serial.h around for 8250.c hardware workarounds. For omap2+, we no longer need mach/serial.h and can make it local to mach-omap2. Signed-off-by: Tony Lindgren <tony@atomide.com>

21 *
22 * Note that using a memory location for storing the UART configuration
23 * has at least two limitations:
24 *
25 * 1. Kernel uncompress code cannot overlap OMAP_UART_INFO as the
26 * uncompress code could then partially overwrite itself
27 * 2. We assume printascii is called at least once before paging_init,
28 * and addruart has a chance to read OMAP_UART_INFO
