mfd: intel_soc_pmic_bxtwc: irq 0 issue, tmu and typec components fail to probe.

[Zhang Ning]

Hi, Greg & Rafael

recently, when I try to enable mfd components for intel_soc_pmic_bxtwc
for debian kernel[0]. I find tmu and typec failed to probe.

after check source code, I find irq for these two devices are 0, when
use platform_get_irq, it will alway fail.

	if (WARN(!ret, "0 is an invalid IRQ number\n"))
		return -EINVAL;
	return ret;

My workaround for debian is to hardcode irq to 0, instead to use api.

I don't know how to write a good solution, thus send an email to you.

BR.
Ning.
