This patch seies introduces support for power managment in the driver as well as vendor specific initialization - registers, clocks, voltage regulators etc.
It includes also a rework for the init sequnce and other PM pre-requisit such as write protection support, handling well-known LUN, error handling (retries), bkops, START_STOP unit command, and ICC levels settings.
