cpufreq: loongson3: Adjust the width of id and val in smc_message

The id field of smc_message is usually stand for the CPU ID. In the past
this driver was only tested for desktop and laptop productions so 4-bits
are enough. But now we have servers that can have as many as 256 cores,
so we need 8-bits CPU ID.

On the other hand, the val field is usually stand for CPU frequency so
12-bits are enough to represent 4GHz, and for higher frequencies there
is an extra bit to extend (enough for 8GHz).

In theory, this is a incompatible change, but fortunately the old SMC
firmwares are not widely shipped and can be updated on the air, thus we
can safely adjust the widths.
