target-ppc: Extend HWCAP2 bits for ISA 3.0
This adds the HWCAP2 bit to detect if a linux user process is
running on an ISA 3.0 compliant cpu like POWER9. This can be
verified using a simple test program that prints the value in
the auxiliary vector for AT_HWCAP2 as shown below.
Before:
$ qemu-ppc64le -cpu power8 test
0x8c000000
$ qemu-ppc64le -cpu power9 test
0x8c000000
After:
$ qemu-ppc64le -cpu power8 test
0x8c000000
$ qemu-ppc64le -cpu power9 test
0x8c800000
