i2c: fix wakeup irq parsing

This patch fixes obvious copy-past error in wake up irq parsing
code which leads to the fact that dev_pm_set_wake_irq() will
be called with wrong IRQ number when "wakeup" IRQ is not
defined in DT.

Fixes: 3fffd1283927 ("i2c: allow specifying separate wakeup interrupt in device tree")
