[PATCH v2] drm/hisilicon: Add load and unload callback functions

[Tian Tao]

Add the callback functions of drm_driver structure member functions
load and unload, no need to call load in the hibmc_pci_probe function
and unload in the hibmc_pci_remove function.

v2:
remove the hibmc_unload called from hibmc_pic_remove.
