fbdev: omap2: improve usage of gpiod API
Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions)
which appeared in v3.17-rc1, the gpiod_get* functions take an additional
parameter that allows to specify direction and initial value for output.
Also make use of gpiod_get*_optional where applicable.
Apart from simplification of the affected drivers this is another step
towards making the flags argument to gpiod_get*() mandatory.
