STM32MP1 core doesn't support ACG feature: GHWCFG4_ACG_SUPPORTED = 0. 
So, in your patch for STM32MP1 at least these lines are no meaning:

+	/* Enable ACG feature in device mode,if supported */
+	dwc2_enable_acg(hsotg);

Looks like you just copied this chirp from dwc2_conn_id_status_change() 
function.

dwc2_hsotg_core_init_disconnected() function is device mode function, 
not sure that it's safe to call it for host mode in dwc2_hcd_init().

Thanks,
Minas
