feat(ff-a): add FFA_MEM_PERM_GET/SET_SMC64

Browse source 
FF-A memory management protocol v1.1 specifies not only
FFA_MEM_PERM_GET_SMC32/FFA_MEM_PERM_SET_SMC32 but also
FFA_MEM_PERM_GET_SMC64/FFA_MEM_PERM_SET_SMC64.

Change former FFA_MEM_PERM_GET/SET definitions to separate operations
and add handler for FFA_MEM_PERM_GET/SET_SMC64 in spmc_smc_handler().
