[PATCH v5 3/7] i2c: core: Switch to fwnode APIs to get IRQ

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

Switch to fwnode APIs to get IRQ. In particular this enables
a support of the separate wakeup IRQ on non-OF platforms.
The rest is converted just for the sake of consistency and
fwnode reuse.
