Subject: [PATCH v4 1/5] mfd: mt6397: create irq mappings in mfd core driver
The core driver should create and manage irq mappings instead of
leaf drivers. This patch change to pass irq domain to
devm_mfd_add_devices() and it will create mapping for irq resources
automatically. And remove irq mapping in rtc driver since this has
been done in core driver.
