Akari Tsuyukusa a09506820a mfd: mt6397: Properly fix CID of MT6328, MT6331 and MT6332 ...

CIDs set for MT6328, MT6331 and MT6332 are not appropriate.
Many Android downstream kernels define CID as below,

MT6328:

    #define PMIC6328_E1_CID_CODE    0x2810
    #define PMIC6328_E2_CID_CODE    0x2820
    #define PMIC6328_E3_CID_CODE    0x2830

MT6331/MT6332:

    #define PMIC6331_E1_CID_CODE    0x3110
    #define PMIC6331_E2_CID_CODE    0x3120
    #define PMIC6331_E3_CID_CODE    0x3130

    #define PMIC6332_E1_CID_CODE    0x3210
    #define PMIC6332_E2_CID_CODE    0x3220
    #define PMIC6332_E3_CID_CODE    0x3230

The current configuration incorrectly uses the revision code as the CID.
Therefore, the driver cannot detect the same PMIC of different revisions.
(E1/E2 for MT6328, E1/E3 for MT6331/MT6332)
Based on these, the CID of MT6328, MT6331 and MT6332 should be corrected.

Additionally, the incorrect MT6331/MT6332 CID overlaps with the MT6320's
actual CID:

    #define PMIC6320_E1_CID_CODE    0x1020
    #define PMIC6320_E2_CID_CODE    0x2020

This causes a conflict in the switch-case statement of mt6397-irq.c,
this prevents adding support for MT6320.
