kernel: defconfig: increase squashfs threads for armv8

Change from 1 squashfs decompression thread per CPU core to 2 threads
per core for armv8 BMCs. This results in a significant speedup during
boot.

Limit this change to only armv8 BMCs since it causes a slowdown on some
armv7 BMCs.

Tested:
Time to multi-user.target on armv8 BMC went from  167.5s -> 148.75s
No change to armv7 kernel .config
