[arm/tegra] provide wifi power/carddetect abstraction

When user switches on wifi, wifi driver need to poweron wifi card and
ask sdhci stack to enumerate the card. Sdhci stack does not provide any
interface to achieve this. Major wifi vendors depend on platform to
provide wifi poweron/reset/carddetect abstraction function.
