[PATCH 02/13] media: i2c: ds90ub960: Fix UB9702 refclk register access

[Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>]

UB9702 has the refclk freq register at a different offset than UB960,
but the code uses the UB960's offset for both chips. Fix this.

The refclk freq is only used for a debug print, so there's no functional
change here.
