[PATCH] backlight: gpio_backlight: Drop output gpio direction check for initial power state

[Ying Liu <victor.liu@nxp.com>]

Bootloader may leave gpio direction as input and gpio value as logical low.
It hints that initial backlight power state should be FB_BLANK_POWERDOWN
since the gpio value is literally logical low.  So, let's drop output gpio
direction check and only check gpio value to set the initial power state.
