Subject: ohci: fix Host Controller USBRESET

ohci: fix Host Controller USBRESET

Specification says that, when entering this state, "the contents of the registers
(except Root Hub registers) are preserved by the HC. [...] The Root Hub is being reset,
which causes the Root Hub's downstream ports to be reset and possibly powered off."
