    intel/skylake: Work around ROMCC optimization bug
    
    On Skylake systems, the bootblock fails to compile with the following
    error message:
    
    bootblock_simple.c:6.1:
    0x13930e0 copy       Internal compiler error: non dominated rhs use point
    0x13a3f70?
    Aborted (core dumped)
    
    The option -fno-simplify-phi works around the issue, but will cause the
    code to use more registers, hence we also need to enable -mcpu=p4 (see
    intel/truxton mainboard for another example of where this has been done
    in the past)
