media: ov5670: Fix probe on ACPI
[ Upstream commit 73b41dc51fbeffa4a216b20193274cfe92b5d95b ]
devm_clk_get() will return either an error or NULL, which the driver
handles, continuing to use the clock of reading the value of the
clock-frequency property.
However, the value of ov5670->xvclk is left as-is and the other clock
framework functions aren't capable of handling error values.
Use devm_clk_get_optional() to obtain NULL instead of -ENOENT.
