This bundle of changes mainly have FF-A framework notification support along with other minor updates and fixes. It adds support to allow multiple UUIDs per partition to register individual SRI callback, to handle Rx buffer full framework notification in particular and general framework/interface to extend in the future. It also adds support for passing UUID in FFA_MSG_SEND2 which improves the multiple UUID/services per partition support in the driver and an helper to check if a partition can receive REQUEST2 messages or not. It also improves cleaning up the partitions by adding unregistration of the devices as well as handles the presence of host partition in the partition info. It also contain fixes big-endian support in couple of functions: __ffa_partition_info_regs_get() and __ffa_partition_info_get(). Big-endian support is still not complete. Only these changes can be verified at the moment without any additional application or testing support changes. Regarding the FF-A versions, it upgrades the driver version to v1.2 and rejects any higher major version than the driver version as incompatible. It also fixes the mis-alignment with sync_send_receive{,2} function prototypes. It replaces UUID buffer to standard UUID format in the ffa_partition_info structure and fixes a typo in some FF-A bus macros.
