[0/6] HDCP SRM interface v2

Message

These patches adds support for SRM loading. SRM has to be saved in a
non-volatile memory(spec) and PSP can't do that directly so we need to
use the driver to do this

Since the kernel cannot directly write to system storage we need to provide an
interface so that the usermode can do it for us
