[PATCH] drm: bridge: rename the function drm_bridge_hpd_notify to drm_bridge_hpd_cb

From: Dafna Hirschfeld
Date: Tue Mar 30 2021 - 07:52:45 EST

drm_bridge_funcs has a function called 'hpd_notify'.
The function drm_bridge_hpd_notify does not call
'hpd_notify' but it calls 'hpd_cb'. This is rather
confusing. Rename the function to fix this confusion.
