  firmware: arm_scmi: Add base notifications support (2020-07-01 17:07:26 +0100)

----------------------------------------------------------------
ARM SCMI/SCPI updates for v5.9

The main addition for this time is the support for platform notifications.
SCMI protocol specification allows the platform to signal events to the
interested agents via notification messages. We are adding support for
the dispatch and delivery of such notifications to the interested users
inside the kernel.

Other than that, there are minor changes like checking and using the
fast_switch capability quering the firmware instead of doing it
unconditionally(using polling mode transfer), cosmetic trace update and
use of HAVE_ARM_SMCCC_DISCOVERY instead of ARM_PSCI_FW.
