UPSTREAM: firmware: arm_ffa: Don't set the memory region attributes for MEM_LEND

As per the FF-A specification: section "Usage of other memory region
attributes", in a transaction to donate memory or lend memory to a single
borrower, if the receiver is a PE or Proxy endpoint, the owner must not
specify the attributes and the relayer will return INVALID_PARAMETERS
if the attributes are set.

Let us not set the memory region attributes for MEM_LEND.
