Cpu: Update Step and Microcode type to uint

Looking at the Redfish Resource and Schema guide:
https://www.dmtf.org/sites/default/files/standards/documents/DSP2046_2021.2.pdf

Section 6.86.6 at page 668, we see:

```
"Manufacturer": "Intel(R) Corporation",
"Model": "Multi-Core Intel(R) Xeon(R) processor 7xxx Series",
"ProcessorId": {
	"VendorId": "GenuineIntel",
	"IdentificationRegisters": "0x34AC34DC8901274A",
        "EffectiveFamily": "0x42",
	"EffectiveModel": "0x61",
        "Step": "0x1",
	"MicrocodeInfo": "0x429943"
},
```

We see that Step and Microcode information should be represented in hex.
To ensure this, we should pass in uint and let the external interface do
the conversion to hex string.

Following Intel specs, Stepping seems to be 1 byte, and Microcode 4.
