[PATCH v1] sdhci: tegra: Remove warnings about missing device-tree properties

Several people asked me about the MMC warnings in the KMSG log and
I had to tell to ignore them because these warning are irrelevant to
pre-Tegra210 SoCs. It should be up to a board's device-tree writer to
properly describe all the necessary properties. Secondly, eventually all
device-tree bindings will be converted to YAML, which allows to validate
board DT files, giving a warning about missing properties. Hence let's
remove the noisy warnings to stop the confusion.
