cpufreq/amd-pstate: Fix the scaling_max_freq setting on shared memory CPPC systems
On shared memory CPPC systems, with amd_pstate=active mode, the change
in scaling_max_freq doesn't get written to the shared memory
region. Due to this, the writes to the scaling_max_freq sysfs file
don't take effect. Fix this by propagating the scaling_max_freq
changes to the shared memory region.
