drm/rockchip: add an common abstracted PSR driver
The PSR driver have exported four symbols for specific device driver, and it's safe to call them in interrupt context: - rockchip_drm_psr_register() - rockchip_drm_psr_unregister() - rockchip_drm_psr_enable() - rockchip_drm_psr_disable() - rockchip_drm_psr_flush() Encoder driver should call the register/unregister interfaces to hook itself into common PSR driver, encoder have implement the 'psr_set' callback which use the set PSR state in hardware side. Crtc driver would call the enable/disable interfaces when vblank is enable/disable, after that the common PSR driver would call the encoder registered callback to set the PSR state. Fb driver would call the flush interface in 'fb->dirty' callback, this helper function would force all PSR enabled encoders to exit from PSR for 3 seconds.
