arm_adi_v5: Rewrite MEM-AP transfer implementation

Browse Source 
Create a single pair of relatively simple functions to handle all variants
of MEM-AP transfers. This replaces the many separate functions that
handled different access sizes and packed or non-packed transfers, which
were all implemented rather differently.

With this single implementation, performance should be more consistent,
regardless of transfer type.
