7 Intead of guarding it with a certain PPC SoC and expanding the list
8 for each SoC requiring it, just guard it with USB_OHCI_BIG_ENDIAN_DESC.

10 This makes it less suprising that passing no_big_frame_no = 1 for the
11 platform data does not do what expected (or
12
13 Checking it for all big endian descriptor setups should not impact
14 performance much as USB1.1 is rather slow anyway.
