Subject: [PATCH v2] mfd: intel_soc_pmic_chtdc_ti: Fix invalid regmap-config max_register value

The max_register = 128 setting in the regmap config is not valid.

The Intel Dollar Cove TI PMIC has an eeprom unlock register at address 0x88
and a number of EEPROM registers at 0xF?. Increase max_register to 0xff so
that these registers can be accessed.

Signed-off-by: Hans de Goede <hdegoede@...hat.com>

Changes in v2:
- Increase max_register to 0xff instead of dropping it so that
  all the registers are shown in debugfs
