[PATCH v3 7/7] usb: mtu3: add optional clock xhci_ck and frmcnt_ck

[Chunfeng Yun]

Add optional clock 'xhci_ck' which is usually the same as sys_ck, but
some SoC use two separated clocks when the controller supports dual
role mode;
Add optional clock 'frmcnt_ck' used on 4nm or advanced process SoC.
