[PATCH 0/3] Implement UFS info protocol to pass additional UIC programming data from platform/silicon specific driver

["Albecki, Mateusz" <mateusz.albecki@intel.com>]

UFS specification allows for additional, implementation specific, programming to be done during host controller initialization. Since some hosts
might require it to allow for device detection we add a way for platform/silicon specific code to pass required attributes and their values to
generic UFS driver. Please see UFS 2.0 specification for details of the host controller initialization sequence(JESD223B section 7.1.1 step 4).
Patchset consists of 3 patches to achieve this. The first one is a bugfix for data transfers that are not aligned to DWORD boundary such as SCSI SENSE
command. The second one is code refactoring for device presence detection that cleans up the function that sends UIC commands. Final patch defines
UFS info protocol and implements driver logic for servicing it.

Tests performed:
-Test UFS LU enumeration with UFS 2.0 card with 3 enabled LUs
-Test that no unaligned data transfers are performed during enumeration
-Test that UIC is programmed according to platform table
-Test that driver operation is not impacted when no UFS info protocol is installed
