arm: tegra: Fix cpu governor change issue

It fixes the issue where cpu governor change
was inconsistent across platforms.

In T2x, AUTO HOTPLUG is disabled therefore we need
to store/restore gov for all online cpus across
LP0 cycle.

In T3x, AUTO HOTPLUG is enabled therefore storing/restoring
gov for Cpu0 across LP0 cycle. Cpu0 remains online in suspend
and resume.
