drm: Add DRM_WEDGE_RECOVERY_COLD_RESET recovery method

Browse source

Introduce DRM_WEDGE_RECOVERY_COLD_RESET (BIT(4)) recovery method to handle
scenarios requiring device power cycle.

This method addresses cases where other recovery mechanisms
(driver reload, PCIe reset, etc.) are insufficient to restore device
functionality. When set, it indicates to userspace that only device power
cycle can recover the device from its current error state.
