media: i2c: ov5647: Add checks for link frequency

Added validation for the link-frequency in the driver.
The new checks ensure that:
- The link-frequency property is present in the device tree
- The number of link frequencies matches the ov5647_link_freqs array size
- The link frequencies in the device tree match the supported
  values in ov5647_link_freqs array

These checks help avoid misconfigurations and prevent
runtime errors due to incorrect declarations
