media: mt9m111: allow to setup pixclk polarity

The chip can be configured to output data transitions on the
rising or falling edge of PIXCLK (Datasheet R58:1[9]), default is on the
falling edge.

Parsing the fw-node is made in a subfunction to bundle all (future)
dt-parsing / fw-parsing stuff.

[[email protected]: Fix inverting clock. INV_PIX_CLOCK bit is set
 per default. Set bit to 0 (enable mask bit without value) to enable
 falling edge sampling.]
[[email protected]: use fwnode helpers]
[[email protected]: mv fw parsing into own function]
[[email protected]: adapt commit msg]
[[email protected]: V4L2 API usage changes to compile
 on media tree master]
