powerpc/85xx: Cleanup how SVR_MAJ() is defined on MPC8536
The MPC8536 seems to use only 3 bits for the major revision field in the SVR rather than the 4 bits used by all other processors. The most significant bit is used as a mfg code on MPC8536. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
