From: Luke Wang <redacted>

The tuning save/restore during system PM is conditioned on
mmc_card_wake_sdio_irq(), but this check is unrelated to whether
tuning values need to be preserved. The actual requirement is that
the card keeps power during suspend and the controller is a uSDHC.

SDIO devices using out-of-band GPIO wakeup maintain power during
suspend but do not set the SDIO IRQ wake flag. In this case the
tuning delay values are not saved/restored.

Remove the unnecessary mmc_card_wake_sdio_irq() condition from both
the suspend save and resume restore paths.
