The index into ov2680_hv_flip_bayer_order[] should be 0-3, but
ov2680_bayer_order() was using 0 + BIT(2) + (BIT(2) << 1) as
max index, while the intention was to use: 0 + 1 + 2 as max index.
Fix the index calculation in ov2680_bayer_order(), while at it
also just use the ctrl values rather then reading them back using
a slow i2c-read transaction.
This also allows making the function void, since there now are
no more i2c-reads to error check.
Note the check for the ctrls being NULL is there to allow
adding an ov2680_fill_format() helper later, which will call
ov2680_set_bayer_order() during probe() before the ctrls are created.
