ENGR00224964-1 Capture: ov5642: 5M mode works at low frame rate

current setting of 5M (QSXGA) mode, sensor works at 2.5fps.
the expected frame rate is 7.5fps.

- use new ov5642 QSXGA firmware get from ov
  change sensor PLL settings 0x3010/0x3012
  QSXGA frame rate changes from 2.5 -- 7.5fps
- change mode between QSXGA@15fps and VGA@15fps go through quick change path.
  modify QSXGA_VGA quick change firmware due to the QSXGA PLL setting changes.
  keep value of 0x3010/0x3012 the same as VGA@15fps original value.
