usb: dwc_otg_310: hcd: assign reg address to hc_regs

Browse Source 
In dwc_otg_hcd_endpoint_disable(), the hc_regs is initialized
to NULL, but never assign a host channel reg address to it,
so the chdis operation can't be handled for ever.

This patch gets a host channenl reg address for hc_regs via
qh->channel->hc_num.
