Subject: [PATCH] mfd: sec: Fix IRQ domain names duplication

For the S2MPG10 IRQ and chained IRQ, regmap IRQ will try to create a
folder with the same name which is impossible and fails with:

  debugfs: ':firmware:power-management:pmic' already exists in 'domains'

Add domain_suffix to the chained IRQ chip driver to fix it.

Fixes: ee19b52c31b3 ("mfd: sec: Use chained IRQs for s2mpg10")
