OMAP3 Turn on the GPIO bank clocks
The function and interface clocks for each GPIO bank, except the first, must be explicitly turned on. These are controlled by the config level defines CONFIG_OMAP3_GPIO_n where n is from 2 to 6. Signed-off-by: Tom Rix <Tom.Rix@windriver.com> Acked-by: Dirk Behme <dirk.behme@googlemail.com>
