I don't really like the casts here, and not really reliable either if
there's ever more fields. I would just store values as little endian in
hw_caps, I doubt it's performance critical.
And why does struct hif_ind_startup use both u32 and __le32? If it's in
little endian it should always use __le types.

No magic values, please. A proper define for bit 0x80 would be nice.
