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)
