spi: let SPI masters ignore their children for PM
Let all SPI masters ignore their children: when it comes
to power management: SPI children have no business doing
keeping their parents awake: they are completely autonomous
devices that just use their parent to talk, and the latter
usecase must be power managed by the host itself on a
per-message basis.
