Revert "usb: dwc2: Move reset into dwc2_get_hwparams()"

This reverts commit 263b7fb557f7 ("usb: dwc2: Move reset into
dwc2_get_hwparams()") due to regression found on bcm2835 platform. USB
ethernet fails, due to being unable to pick up proper parameters when
performing a plain reset before reading hw params.

Below shows the results of the gnptxfsiz and hptxfsiz with and before
and after reverting this (from Stefan Wahren):

So here is the probe result before Patch 1 is applied:

[    1.283148] dwc2 20980000.usb: Configuration mismatch. dr_mode forced to host
[    1.313894] dwc2 20980000.usb: gnptxfsiz=00201000

And here is the probe result after Patch 1 is applied:
