Originally the cpuid var the value gets read into was defined as
   u8 cpuid[RK3399_CPUID_LEN];
hence the sizeof(cpuid) would return the correct the correct number
of array elements.
With the move to a separate function cpuid becomes a pointer and
sizeof(cpuid) hence returns the pointer size - 8 in the arm64 case.
We do have the actual id length available as function param so use
it for actual amount of bytes to read.
