[PATCH 1/5] usb: dwc2: Make dwc2_wait_bit_set wait all bits in mask

[Jules Maselbas]

The dwc2_wait_bit_set() wasn't waiting for all bits in the mask to be
set but was waiting for only one bit set a mask.
This is not the expected behavior as stated in the function's comment.

The function dwc2_wait_bit_set() is always called with a mask of only
one bit.
