sdm660_64/sdm630_64: cleanup cpuset configuration

Browse source 
The following changes are made to simplify the cpuset
configuration.

(1) Earlier kernels used to ignore any offline CPUs specified
in the cpuset/cpus file. As there is no gaurantee that all
gold cluster CPUs are online during init, silver cluster
cpumask is written to cpuset/cpus file before writing the
all possible cpumask. Recent kernels have support to handle
offline CPUs written to cpuset/cpus file. When the CPU
becomes online, the cpuset setting is applied. So apply
the setting for a cpuset cgroup once.

(2) Both SDM660 and SDM630 share the same device project,
so move the final cpuset configuration to post-boot. This
allows different cpuset settings for these two targets. This
also improves boot-up performance as we apply the cpuset
restrictions after the booting is completed. This policy
is already in place for other targets like MSM8998.
