ARM: OMAP: Palm Tungsten E board update 



General update of the board file for Palm Tungsten E. Registers the
platform devices contained in the PDA (ROM chip, keypad, infra-red)
and updates the configuration for USB and MMC, whose config values
were previously guessed in most cases due to lack of documentation
(and now are confirmed by a number of users). Macros for GPIO pins are
moved to a file in include/asm-arm/arch-omap.
