media: camera: Update conftest for gpio_device_find

Browse Source 
When adding conftest tests for detecting if specific functions are
present, it is always better to check if the newly added function is
present versus the function that has been removed. The reason being that
is the newly added function is modified in the future then the conftest
tests can be extended to check for updates to the function.

Therefore, instead of checking if the function gpiochip_find() is
present, which was removed in Linux v6.7, check if the function
gpio_device_find() is present, which replaced gpiochip_find in Linux
v6.7.
