mfd: twl4030-power: Fix pmic for boards that need vmmc1 on reboot
commit ad48ed0c5763dc08931407e455dff5acdbe96e81 upstream.
At least two different omap3630/3730 boards booting from MMC1
fail to reboot if the "ti,twl4030-power-idle-osc-off" or
"ti,twl4030-power-idle" compatible flags are set. This patch will
keep the vmmc1 powered up during reboot allowing the bootloader
to load.
