powerpc/book3s64: Always build for power4 or later
When we're not compiling for a specific CPU, ie. none of the
CONFIG_POWERx_CPU options are set, and CONFIG_GENERIC_CPU *is* set, we
currently don't pass any -mcpu option to the compiler. This means the
compiler builds for a "generic" Power CPU.
But back in 2014 we dropped support for pre power4 CPUs in commit
468a33028edd ("powerpc: Drop support for pre-POWER4 cpus").
Given that, there's no point in building the kernel to run on pre power4
cpus. So update the flags we pass to the compiler when
CONFIG_GENERIC_CPU is set, to specify -mcpu=power4.
