[PATCH v1 1/7] mfd: intel_soc_pmic_bxtwc: fix TMU interrupt index

[sathyanarayanan.kuppuswamy@xxxxxxxxxxxxxxx]

From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@xxxxxxxxxxxxxxx>

TMU interrupts are registered as a separate interrupt chip, and
hence it should start its interrupt index(BXTWC_TMU_IRQ) number
from 0. But currently, BXTWC_TMU_IRQ is defined as part of enum
bxtwc_irqs_level2 and its index value is 11. Since this index
value is used when calculating .num_irqs of regmap_irq_chip_tmu,
it incorrectly reports number of irqs as 12 instead of actual
value of 1.

static const struct regmap_irq bxtwc_regmap_irqs_tmu[] = {
	REGMAP_IRQ_REG(BXTWC_TMU_IRQ, 0, 0x06),
};

static struct regmap_irq_chip bxtwc_regmap_irq_chip_tmu = {
	.name = "bxtwc_irq_chip_tmu",
	.status_base = BXTWC_TMUIRQ,
	.mask_base = BXTWC_MTMUIRQ,
	.irqs = bxtwc_regmap_irqs_tmu,
	.num_irqs = ARRAY_SIZE(bxtwc_regmap_irqs_tmu),
	.num_regs = 1,
};

This patch fixes this issue by creating new enum of tmu irqs and
resetting its starting index to 0.
