firmware: arm_ffa: Stash the partition properties for query purposes
The properies obtained from the partition information descriptor as
part of initial partitions discovery is useful as it contain info
if the partition
- Runs in AArch64 or AArch32 execution state
- Can send and/or receive direct requests
- Can send and receive indirect message
- Does support receipt of notifications.
These can be used for querying before attempting to do any of the
above operations.
