[PATCH 1/7] media: i2c: ov7251: Fix link frequency index

[Antoine Pichot <antoine.pichot@gmail.com>]

ov7251_check_hwcfg() stores i, the index into the firmware's
link_frequencies array, in link_freq_idx, which the driver then uses to
index its own link_freq[], pixel_rates[] and pll1[] tables. The matching
driver entry is j. Store j.

Observed on a Surface Book 2, where ipu-bridge lists one link frequency,
319.2 MHz, which is link_freq[1]: V4L2_CID_LINK_FREQ reads 240000000,
and the pixel rate and PLL registers are off the same way.
