ALSA: pcm: use the same dma mmap codepath both for arm and arm64

This avoids following kernel crash when try to playback on arm64

[  107.503405] [<ffffffc0001541ac>] __do_fault+0xb0/0x498
[  107.508565] [<ffffffc0001576a0>] handle_mm_fault+0x224/0x7b0

[  107.519738] [<ffffffc000081100>] do_mem_abort+0x38/0x98

Tested: backported to 3.14 and tried to playback on arm64 machine
