[PATCH 6.18.y 3/3] media: imx219: Account for rate_factor in control steps

[Sasha Levin <sashal@kernel.org>]

From: Sakari Ailus <sakari.ailus@linux.intel.com>

[ Upstream commit 57043aef0a04bd96d97881422590e71c1e4c45b1 ]

The controls that are divided by the rate_factor before writing them to
the registers have the step of the value of the rate_factor. Take this
into account when the control's range is modified. The controls are
created in a configuration where rate_factor is always 1, hence there's no
need to change the code adding new controls.
