cpufreq: loongson3: Replace IOCSR read/write with MMIO ones
Our server productions (e.g. Loongson-3D6000/3E6000) can have multiple
nodes in one package and SMC mailboxes are also per-node. However, IOCSR
read/write can only perform on the current node, while sometimes we want
to perform on other nodes (e.g. when switch governor, the get and target
callbacks are not run on target core). So replace IOCSR read/write with
MMIO ones.
