From: Nicolas Boichat <drinkcat@chromium.org>
[ 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.
