Subject: [PATCH V2] media: ov5640: Fix check for PLL1 exceeding max allowed rate

The PLL calculation routine checks the wrong variable name 'rate'
when it should be called '_rate' when checking to see whether or
not the PLL1 output frequency exceeds 1GHz.

This patch changes it to the correct variable '_rate'
