This enables the property post_ios_power_on. With this property, the driver pwrseq_simple will do its entire power sequence at the end of the mmc_power_up() function. The property pre-power-on-delay-ms adds a delay of 1ms between the enablement of the clk and the assertion of the reset line. It fixes the power-up sequence for the Wifi chipset AP6335.
