[PATCH v3 05/15] media: mt9m114: Fix default hblank and vblank values

[Hans de Goede <hansg@kernel.org>]

The current default hblank and vblank values are based on reaching 30 fps
with the pixel-array outputting 1280x960, but the default format for
the pixel-array source pad and the isp sink pad is 1296x976, correct
the default hblank and vblank values to take this into account.

Changes in v2:
- Update comment about resolution / pixrate / FPS to:
 * Set the default to achieve full resolution (1296x976 analog crop
 * rectangle, 1280x960 output size) at 30fps with a 48 MHz pixclock.
