[U-Boot] [PATCH] ARM: twister: add missing gpio clock init

[Jeroen Hofstee]

Commit f33b9bd3984fb11e1d8566a866adc5957b1e1c9d breaks boards
which do not explicitly enable the gpio clocks. This causes
the twister spl to hang, since it uses the no longer enabled
gpio 55. Add CONFIG_OMAP3_GPIO_2 to unbrick the board.
