[PULL 38/41] target/ppc: Use PPC2_ISA207 instead of PPC2_ISA207S

[Harsh Prateek Bora <harshpb@linux.ibm.com>]

From: Chinmay Rath <rathc@linux.ibm.com>

PPC2_ISA207S is only ever set in the CPUPPCState's insns_flags2
alongside PPC2_ISA207. Checks made by PPC2_ISA207S could be
replaced with PPC2_ISA207, hence rendering it useless and apt for
removal. This patch does the same.
