soc/mediatek/mt8186: Enable USB macro control
When powering down SSUSB, the system needs to wait the ACK from SSUSB.
We found that the setting of USB PAD top macro is not correct and
it will cause timeout waiting for the ACK from SSUSB.
To resolve this, we add mt_pll_set_usb_clock() in pll.c to enable usb
macro control for powering down SSUSB.
TEST=timeout of ssusb powerdown ack does not occur.
