ufs: query descriptor API
Introduces the API for sending queries with descriptors. A descriptor is a block or page of parameters that describe the device. The descriptors are classified into types and can range in size from 2 bytes through 255 bytes. All descriptors have a length value as their first element, and a type identification element as their second byte. All descriptors are readable and some may be write once. They are accessed using their type, index and selector. Signed-off-by:Dolev Raviv <draviv@codeaurora.org> Signed-off-by:
