omap: Eliminate OMAP_MAX_NR_PORTS

Browse Source 
Eliminate OMAP_MAX_NR_PORTS

Note that also the null terminator entry for omap1
serial_platform_data needs to be now removed to avoid
oopsing.

Note that mach-omap1 uses struct plat_serial8250_port
array, which requires a null terminator at the end,
and that's why we need to use ARRAY_SIZE - 1. This
is not needed on mach-omap2 as the array used is
struct omap_uart_state, and does not use a null
terminator.
