getcpu detects cpu vendor and model information

getcpu is a function that uses the cpuid instruction to detect the cpu vendor string and model information and formats it into a readable string

Parameters

buffer,the	output buffer for the cpu description string
buffer_len,the	size of the output buffer

using getcpu is done with

#include "../kernel/cpu.h" //or just cpu.h
char cpu[64];
getcpu(cpu, sizeof(cpu));
