Add support for CM-T54 CoM and SBC-T54 board:

http://compulab.co.il/products/computer-on-modules/cm-t54/
http://compulab.co.il/products/sbcs/sbc-t54/

SBC-T54 is a single board computer based on OMAP5432 CPU.
It is implemented with a CM-T54 CoM providing most of the functions,
and SB-T54 carrier board providing connectors and several additional
functions.

Added basic support for:

* PMIC
* LED
* MMC/SD
* eMMC
* USB
* I2C1/4
* SB-T54 and CM-T54 EEPROMs
* RTC

You probably want to use the OMAP5_CORE_IOPAD and OMAP5_WKUP_IOPAD
macros for new boards as then you can easily check them against
the TRM based on the physical offset of the register.

Tony
