Subject: [PATCH] USB: OHCI: allow other arches to use the BE frame number
quirk
Intead of guarding it with a certain PPC SoC and expanding the list
for each SoC requiring it, just guard it with USB_OHCI_BIG_ENDIAN_DESC.
This makes it less suprising that passing no_big_frame_no = 1 for the
platform data does not do what expected (or
Checking it for all big endian descriptor setups should not impact
performance much as USB1.1 is rather slow anyway.
