USB: EHCI support for big-endian descriptors
This patch implements supports for EHCI controllers whose in-memory data structures are represented in big-endian format. This is needed (unfortunately) for the AMCC PPC440EPx SoC EHCI controller; the EHCI spec doesn't specify little-endian format, although that's what most other implementations use. The guts of the patch are to introduce the hc32 type and change all references from le32 to hc32. All access routines are converted from cpu_to_le32(...) to cpu_to_hc32(ehci, ...) and similar for the other "direction". (This is the same approach used with OHCI.) David fixed: Whitespace fixes; refresh against ehci cpufreq patch; move glue for that PPC driver to the patch adding it; fix free symbol capture bugs in modified "constant" macros; and make "hc32" etc be "le32" unless we really need the BE options, so "sparse" can do some real good.
