mfd: rohm: Factor out power button registration

Factor out the power button registration logic using software nodes
from rohm-bd718x7 and rohm-bd71828 drivers into a shared module
rohm-pwrbutton.

This reduces duplication and makes it easier to support other ROHM
PMICs with similar power button configurations.
