The newly added driver has incorrect #ifdef annotations on its
PM functions, leading to a harmless compile-time warning when
CONFIG_PM is disabled:
drivers/media/platform/rockchip/rga/rga.c:760:13: error: 'rga_disable_clocks' defined but not used [-Werror=unused-function]
static void rga_disable_clocks(struct rockchip_rga *rga)
^~~~~~~~~~~~~~~~~~
drivers/media/platform/rockchip/rga/rga.c:728:12: error: 'rga_enable_clocks' defined but not used [-Werror=unused-function]
This removes the #ifdef and marks the functions as __maybe_unused,
so gcc can silently drop all the unused code.
