media: platform: rzg2l-cru: Use %pe format specifier

The %pe format specifier is designed to print error pointers. It prints
a symbolic error name (eg. -EINVAL) and it makes the code simpler by
omitting PTR_ERR().

This patch fixes this cocci report:
./platform/renesas/rzg2l-cru/rzg2l-csi2.c:307:30-37: WARNING: Consider using %pe to print PTR_ERR()
./platform/renesas/rzg2l-cru/rzg2l-csi2.c:726:30-37: WARNING: Consider using %pe to print PTR_ERR()
