From: Sinthu Raja <sinthu.raja@ti.com>
The SK architecture comprises of baseboard and a SOM board. The
AM68 Starter Kit's baseboard contains most of the actual connectors,
power supply etc. The System on Module (SoM) is plugged on to the base
board. Therefore, add support for peripherals brought out in the base
board.

Changes in V3:
*Addressed the review comments:
- Removed the unused nodes that are disabled by default.
- Updated the gpio regulator node: gpio-regulator-tlv to "regulator-tlv".
