[PATCH] linux-user: Add PowerPC ISA 3.1 and MMA to hwcap

[Joel Stanley]

These are new hwcap bits added for power10.

MMA support for TCG is on the list so I think it makes sense for this to
land after those are merged.

I tested my patch with this program:

 https://github.com/shenki/p10_tests

$ qemu-ppc64le -cpu power10  -L ~/ppc64le/ ./test -c
HWCAP: 0x58000580 HWCAP2: 0x8ee60000
ISAv3.1: Yes
MMA: Yes

$ qemu-ppc64le -cpu power9  -L ~/ppc64le/ ./test -c
HWCAP: 0x58000580 HWCAP2: 0x8ee00000
ISAv3.1: No
MMA: No
