UPSTREAM: firmware: arm_ffa: Switch to using ffa_mem_desc_offset() accessor

Browse Source 
In preparation to add support to the new memory transaction descriptor,
the ep_mem_access member needs to be removed and hence even the macro
COMPOSITE_OFFSET(). Let us switch to using the new ffa_mem_desc_offset()
accessor in ffa_setup_and_transmit().

This will enable adding the support for new format transparently without
any changes here again.

(cherry picked from commit e4607b84c6)
