cpufreq/amd-pstate: Don't update CPPC request in amd_pstate_cpu_boost_update()
[ Upstream commit 67c08d303e0a1a5665b3f198037c9fae2d808090 ]
When boost is changed the CPPC value is changed in amd_pstate_cpu_boost_update()
but then changed again when refresh_frequency_limits() and all it's callbacks
occur. The first is a pointless write, so instead just update the limits for
the policy and let the policy refresh anchor everything properly.
