mfd: mt6397: Do not call irq_domain_remove if PMIC unsupported

[ Upstream commit a177276aa098aa47a100d51a13eaaef029604b6d ]

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.
