meta-ampere: mtmitchell: update CPU presence object paths

Currently, the gpio-presence is configured to create CPU_1/2 object
paths when sockets 0/1 are present. But the SMBIOS service creates
cpu0/1 object paths to indicate sockets 0/1 are present.
By the mismatch between gpio-presence and SMIBIOS services, adc sensors
that depend on the "CPURequired" property in EM can be missed.

This commit updates the object path of CPU presence to synchronize
gpio-presence and SMBIOS services to avoid the issue.

Tested:
    1. PLDM sensors work correctly on both 1P and 2P systems.
    2. ADC sensors are shown correctly.
