[PATCH 1/3] rkisp1: Get rid of unused variable warning

If CONFIG_OF is not selected, the compiler will complain:

drivers/staging/media/rkisp1/rkisp1-dev.c: In function ‘rkisp1_probe’:
drivers/staging/media/rkisp1/rkisp1-dev.c:457:22: warning: unused variable ‘node’ [-Wunused-variable]
457 | struct device_node *node = pdev->dev.of_node;

Rework the code slightly and make the compiler happy.
