mfd: sec-irq: s2dos05 doesn't support interrupts

The commit bf231e5febcf ("mfd: sec-core: Add support for the Samsung
s2dos05") adding s2dos05 support didn't add anything related to IRQ
support, so I assume this works without IRQs.

Rather than printing a warning message in sec_irq_init() due to the
missing IRQ number, or returning an error due to a missing irq chip
regmap, just return early explicitly.

This will become particularly important once errors from sec_irq_init()
aren't ignored anymore in an upcoming patch and helps the reader of
this code while reasoning about what the intention might be here.
