Subject: [PATCH v1 3/9] mfd: intel_soc_pmic_crc: Use devm_regmap_add_irq_chip()

Use devm_regmap_add_irq_chip() to simplify the code.

While at it, replace -1 magic parameter by PLATFORM_DEVID_NONE when
calling mfd_add_devices().

Note, the mfd_add_devices() left in non-devm variant here due to
potentially increased churn while wrapping pwm_remove_table().
