The series mainly adds support for FFA_MSG_SEND2. When trying to add
the support for the same, it was found that currently we don't check
the properties of the partitions before sending any direct messages
or registering notification callbacks.

Support for checking if the partition can receive notifications and
direct requests before sending the same can be added by stashing the
discovered partition properties for later query purposes.

Rx buffer full notification support is not yet added as the details of
the usecase are still be thought through.
