Dhananjay Ugwekar 8552150e5d cpufreq/amd-pstate: Fix amd_pstate mode switch on shared memory systems
[ Upstream commit c10e50a469b5ec91eabf653526a22bdce03a9bca ]

While switching the driver mode between active and passive, Collaborative
Processor Performance Control (CPPC) is disabled in
amd_pstate_unregister_driver(). But, it is not enabled back while registering
the new driver (passive or active). This leads to the new driver mode not
working correctly, so enable it back in amd_pstate_register_driver().

Fixes: 3ca7bc818d ("cpufreq: amd-pstate: Add guided mode control support via sysfs")
