Now that we can have the removable UFS cards which can be plugged in/out
at runtime, we need to add the support for gpio based card
insertion/removal event detection support. But this is bit complicated
as current platforms have the combo card slot which can either take UFS
or SD card at one time and there is a single GPIO assigned for card detect
event. This means we need some module which takes the responsibility of
controlling (configuration, interrupt handling) this shared card detection
GPIO and pass card detection event to both UFS and SD card drivers so they
can probe to see what card is inserted. Kernel already have the extcon-gpio
module which can be used as gpio control module and can pass the card
detection event to both UFS & SD card drivers. So UFS driver registers the
notification callback with extcon driver and tries to detect/remove the UFS
card.

Add MSM UFS host PHY driver which binds with UFSHCD platform
driver exposing vendor specific operations to initialize the
PHY. Since the controller and PHY are tightly coupled in the
system, some of the MSM specific controller register
configuration is also applied inline while initializing PHY.
Add a new compatible property "qcom,ufshc" which specifies the
UFS host controller on MSM platforms. The UFS controller driver
binds with UFS PHY driver using the phandle reference of PHY
devicetree node.

The clocks for UFS device will be managed by generic DVFS (Dynamic
Voltage and Frequency Scaling) framework within kernel. This devfreq
framework works with different governors to scale the clocks. By default,
UFS devices uses simple_ondemand governor which scales the clocks up if
the load is more than upthreshold and scales down if the load is less than
downthreshold.

This patch adds support for Universal Flash Storage(UFS)
host controllers. The UFS host controller driver
includes host controller initialization method.
The Initialization process involves following steps:
- Initiate UFS Host Controller initialization process by writing
to Host controller enable register
- Configure UFS Host controller registers with host memory space
datastructure offsets.
- Unipro link startup procedure
- Check for connected device
- Configure UFS host controller to process requests
- Enable required interrupts
- Configure interrupt aggregation
