usb: dwc2: Changes in registers backup/restore functions
Move hptxfsiz to host register's backup/restore functions, not
needed to have it in global register's backup/restore functions.
Add backup for glpmcfg, and read/write for gi2cctl and pcgcctl.
As requires programming guide.
Affected functions:
dwc2_backup_host_registers()
dwc2_restore_host_registers()
dwc2_backup_global_registers()
dwc2_restore_global_registers()
