[PATCH v3 1/3] xen/ppc: Bump minimum target ISA to 3.0 (POWER9)

[Shawn Anastasio <sanastasio@xxxxxxxxxxxxxxxxxxxxx>]

In preparation for implementing ISA3+ Radix MMU support, drop ISA 2.07B
from the supported ISA list to avoid having a non-working
configuration in tree. It can be re-added at a later point when Hash
MMU support is added.
