[U-Boot] [PATCH] OMAP3: Introduce CONFIG option for power code

[Dirk Behme <dirk.behme@googlemail.com>]

Some OMAP3 boards need control for external power companion
chips. Introduce a CONFIG option for this, to avoid Makefile
changes for each board.

Compile tested with ./MAKEALL ARM_CORTEX_A8, boot tested on
OMAP3 based BeagleBoard.

+CONFIG_OMAP3_POWER
+
+Some OMAP3 boards use external power companion chips to be configured. Enable
+this CONFIG option in your board specific configuration file if your board
+uses such a companion chip.
+
+This enables compilation of board/omap3/common/power.c.
