rockchip: misc: read the correct number of bytes from the

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.
