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.
