gc2: es: Modify DIMM sensor channel to match with GC2.0 MB

[pabloyangWW]

[Task Description]
This patch updates DIMM sensor naming convention to align with hardware configuration. The sensor names are modified from A0/A2/A4/A6 to A2/A3/A6/A7 to accurately reflect the actual DIMM slot positions on the motherboard.

[Motivation]
The original sensor naming (DIMMA0, DIMMA2, DIMMA4, DIMMA6) did not match the physical DIMM slot layout on GC2 platform. This caused confusion during system monitoring and debugging. The corrected naming (DIMMA2, DIMMA3, DIMMA6, DIMMA7) ensures sensor names correspond to actual hardware slots, improving maintainability and reducing potential misidentification of DIMM-related issues.

[Design]

1. Modified DIMM temperature sensors via PECI (0x06, 0x07, 0x0A, 0x0B):

   • SENSOR_NUM_TEMP_DIMM_A2 (0x06): DIMM A2 channel 2
   • SENSOR_NUM_TEMP_DIMM_A3 (0x07): DIMM A3 channel 3
   • SENSOR_NUM_TEMP_DIMM_A6 (0x0A): DIMM A6 channel 6
   • SENSOR_NUM_TEMP_DIMM_A7 (0x0B): DIMM A7 channel 7 Using Intel PECI interface with pre-read handlers for DIMM presence check

2. Modified DIMM PMIC power sensors (0x40-0x43):

   • SENSOR_NUM_PWR_DIMMA2_PMIC (0x40): DIMM A2 power
   • SENSOR_NUM_PWR_DIMMA3_PMIC (0x41): DIMM A3 power
   • SENSOR_NUM_PWR_DIMMA6_PMIC (0x42): DIMM A6 power
   • SENSOR_NUM_PWR_DIMMA7_PMIC (0x43): DIMM A7 power Using PMIC driver with proper initialization arguments

[Test Result]
Tested on GC2-ES platform, all DIMM sensors reporting correctly with proper naming :
