nomahans and pxa27x IIRC for usb host

IIRC trizepsiv
but other HW (mainline) can activate it also evenif they do not actually
by default

yes a real problem because you will have to deal with is latter anyway
and it will take hours to debug. So do a quick dirty fix will not improve
the situation at the end.

Also define a register the pxa specific is alread the principle fallow in this

which not mean that we do support the pxa2xx usb (trizepsiv)
