media: cx23885: Set subdev host data to clk_freq pointer
[ Upstream commit 5ceade1d97fc6687e050c44c257382c192f56276 ]
Currently clk_freq is ignored entirely, because the cx235840 driver
configures the xtal at the chip defaults. This is an issue if a
board is produced with a non-default frequency crystal. If clk_freq
is not zero the cx25840 will attempt to use the setting provided,
or fall back to defaults otherwise.
