Michael Grzeschik c8879d3f87 phy: stm32-usphyc: add 200 to 300 us delay to fix timeout on some machines
An minimum udelay of 200 us seems to be necessary on some machines. After
the setup of the pll, which needs about 100 us to be locked there seem
to be additional 100 us to get the phy really functional. Without this
delay the usb runs not functional. With this additional short udelay
this issue was not reported again.
