powerpc: Add POWER9 cputable entry
Add a cputable entry for POWER9. More code is required to actually
boot and run on a POWER9 but this gets the base piece in which we can
start building on.
Copies over from POWER8 except for:
- Adds a new CPU_FTR_ARCH_300 bit to start hanging new architecture
features from (in subsequent patches).
- Advertises new user features bits PPC_FEATURE2_ARCH_3_00 &
HAS_IEEE128 when on POWER9.
- Drops CPU_FTR_SUBCORE.
- Drops PMU code and machine check.
