Tao Huang d92ea942e0 ARM: rv1126_defconfig: Replace CONFIG_SQUASHFS_DECOMP_MULTI_PERCPU by CONFIG_SQUASHFS_DECOMP_MULTI
The squashfs multi CPU decompressor makes use of get_cpu_ptr() to
acquire a pointer to per-CPU data. get_cpu_ptr() implicitly disables
preemption which serializes the access to the per-CPU data.

But decompression can take quite some time depending on the size. The
observed preempt disabled times in real world scenarios went up to 32ms,
causing massive wakeup latencies. This happens on all CPUs as the
decompression is fully parallelized.

So replace CONFIG_SQUASHFS_DECOMP_MULTI_PERCPU by CONFIG_SQUASHFS_DECOMP_MULTI.
