Subject: [PATCH 3/4] media: ov08x40: Rename ext_clk to xvclk

The data-sheet and documentation for this part uses the name xvclk not
ext_clk for the input reference clock. Rename the variables and defines in
this driver to align as preparation for adding DT support where the name of
the clock in DT will be "xvclk".
