Setting the bias. 2. Different configuration register. 3. Not enabling the low-sys DAC. 4. Using same regmap for PMIC and haptic blocks. Incorporate all differences into max77693 haptic driver so both devices can be supported.

Add table of device ids and store current device type for later usage. 2. Differentiate the haptic device configuration.

The field, after initialization, is only read so this only obfuscates the code. Remove the field and use directly enum value.

Move the state container to common header file. Additionally add consistent 'i2c' prefixes to its members (of 'struct i2c_client' type).
