mfd: mt6397: Do not call irq_domain_remove if PMIC unsupported
If the PMIC ID is unknown, the current code would call irq_domain_remove and panic, as pmic->irq_domain is only initialized by mt6397_irq_init. Return immediately with an error, if the chip ID is unsupported. Signed-off-by: Nicolas Boichat <drinkcat@chromium.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
