[PATCH 6.19 577/844] media: i2c: ov01a10: Fix reported pixel-rate value

[Sasha Levin]

From: Hans de Goede <hansg@xxxxxxxxxx>

[ Upstream commit 9c632eebf6af4cb7b0f85503fe1ebc5176ff0db1 ]

CSI lanes are double-clocked so with a single lane at 400MHZ the resulting
pixel-rate for 10-bits pixels is 400 MHz * 2 / 10 = 80 MHz, not 40 MHz.

This also matches with the observed frame-rate of 60 fps with the default
vblank setting: 80000000 / (1488 * 896) = 60.

Fixes: 0827b58dabff ("media: i2c: add ov01a10 image sensor driver")
