drm/msm/gpu: Avoid -Wunused-function with !CONFIG_PM_SLEEP
When building with CONFIG_PM=y and CONFIG_PM_SLEEP=n (such as ARCH=riscv allmodconfig), the following warnings/errors occur: drivers/gpu/drm/msm/adreno/adreno_device.c:679:12: error: 'adreno_system_resume' defined but not used [-Werror=unused-function] 679 | static int adreno_system_resume(struct device *dev) | ^~~~~~~~~~~~~~~~~~~~ drivers/gpu/drm/msm/adreno/adreno_device.c:655:12: error: 'adreno_system_suspend' defined but not used [-Werror=unused-function] 655 | static int adreno_system_suspend(struct device *dev) | ^~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors These functions are only used in SET_SYSTEM_SLEEP_PM_OPS(), which evaluates to empty when CONFIG_PM_SLEEP is not set, making these functions unused. To resolve this, use the SYSTEM_SLEEP_PM_OPS() and RUNTIME_PM_OPS() macros, which were introduced in commit 1a3c7bb08826 ("PM: core: Add new *_PM_OPS macros, deprecate old ones"). They are designed to avoid these compiler warnings while still guarding their use on CONFIG_PM{,_SLEEP}=y.
