libfdt: Change names of sparse helper macros
The default libfdt_env.h (for POSIXish userland builds) supports sparse checking. It has a couple of helper macros, __force and __bitwise which expand the relevant sparse attributes to enable checking for incorrect or missing endian conversions. Those are bad names: for one, leading underscores are supposed to be reserved for the system libraries, and worse, some systems (including RHEL7) do define those names already. So change them to FDT_FORCE and FDT_BITWISE which are far less likely to have collisions. Suggested-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
