mmc: sdhci-pltfm: dt device does not pass parent to sdhci_alloc_host
Neither platform based nor dt based device needs to pass the parent
to sdhci_alloc_host. There is no difference between platform and dt
on this point.
The patch makes the change to pass device itself than its parent to
sdhci_alloc_host for dt case too. Otherwise the probe function of
sdhci based drivers which is shared between platform and dt will
fail on dt case.
