LoongArch: Remove clock setting during cpu hotplug stage
On physical machine we can save power by disabling clock of hot removed
cpu. However as different platforms require different methods to
configure clocks, the code is platform-specific, and probably belongs to
firmware/pmu or cpu regulator, rather than generic arch/loongarch code.
Also, there is no such register on QEMU virt machine since the
clock/frequency regulation is not emulated.
This patch removes the hard-coded clock register accesses in generic
LoongArch cpu hotplug flow.
