ALSA: pcm: use the same dma mmap codepath both for arm and arm64
This avoids following kernel crash when try to playback on arm64
[ 107.497203] [<ffffffc00046b310>] snd_pcm_mmap_data_fault+0x90/0xd4
[ 107.503405] [<ffffffc0001541ac>] __do_fault+0xb0/0x498
[ 107.508565] [<ffffffc0001576a0>] handle_mm_fault+0x224/0x7b0
