Process a FF-A FFA_MEM_SHARE message coming from a SP or being sent
from the Normal world with one or more SPs receivers.
FFA_MEM_SHARE is used to share a memory region from an endpoint (SP or
normal world) with one or more endpoints in secure world(SPs).
A simplified version of the share memory transaction descriptor looks
like the following:
|-------------------|
|ffa_mem_transaction| Contains general data for the whole share
|-------------------|
|mem_access_array[0]| Contains information specific for each receiver SP
|-------------------|
|mem_access_array[1]|
|-------------------|
|mem_access_array[n]|
|-------------------|
|ffa_mem_region | Contains the memory which is shared
|-------------------|
Add sp_mem as a new memory object. Sp_mem is used to store all
information needed for a FF-A share. For each new FF-A share a sp_mem
object is created. Each share is stored inside the mem_shares list
inside sp_mem.c
The ffa_mem_transaction data is stored inside the sp_mem object.
The receivers list inside sp_mem is used to store all the
ffa_mem_region related data.
The regions list is used to store all data related to the
mem_access_array. A mobj reference is will be used to map the region
into the SPs endpoint.
