arm: mach-omap2: am33xx: Init pinmux before clock
The board_early_init_f() inits clock before initing pinmux. However,
the clock configuration code might need to adjust PMIC settings of a
PMIC on I2C bus (e.g. board/ti/am335x/board.c does that). If the I2C
bus pin muxing is not configured before attempting to communicate
with the PMIC, the communication will silently fail and the prcm_init()
may configure fast enough CPU clock that the default voltage provided
by the PMIC would be insufficient and the platform would become
unstable.
