drm/xe/huc: Extract version and binary offset from new HuC headers
The GSC-enabled HuC binary starts with a GSC header, which is followed
by the legacy-style CSS header and the binary itself. We can parse the
GSC headers to find the HuC version and the location of the binary to
be used for the DMA transfer.
The parsing function has been designed to be re-used for the GSC binary,
so the entry names are external parameters (because the GSC uses
different ones) and the CSS entry is optional (because the GSC doesn't
have it).
v2: move new code to uc_fw.c, better comments and error checking, split
old code move to separate patch (Lucas), move headers and
documentation to uc_fw_abi.h.
v3: use 2 separate loops, rework marker check (Lucas)
