setbits_le32() is not really arch-specific... the arch-specific part of
accessing memory is wrapped by readl() and writel(), and the endianness
can be accounted for with the right macros. Generalize the definitions,
add a be32 version and move them to endian.h so that all platforms can
use them. Also include endian.h from libpayload.h so we won't update any
payload's old use of the macros (endianness is something useful enough
to always have avalable anyway, and shouldn't clash with other things).
This also fixes a bug where these macros would only be available if
libpayload-config.h had been independently included before.
Also fix a bug with readl() macros on all archs where they refused to
work on const pointers (which they should).
