Previously I had added the support to sdhci-of-arasan driver with a separate phy driver[1]. Since then it has turned out that tuning operation (for HS200, HS400 and SDR104 speed modes) will require configuration of phy registers. This completely breaks the model of the sdhci-of-arasan driver which relies on a separate driver to configure the phy register space. Because of this, I am creating a new driver with both the sdhci and phy register spaces. This helps me use the phy registers in a future patch that adds tuning support. DT patches will be posted in a separate series. Changes in v3: 1. Removed reference to clk_ahb as its not being used. 2. Added comment for pm_runtime being used for enabling clocks. Changes in v2: 1. Reset OTAP delay back to default value in init. 2. Improved patch description for patch 2. 3. Minor style fixes.
