pcm: dmic: assembly: add x32 support.

[GitHub pull_request - opened]

alsa-project/alsa-lib pull request #61 was opened from hvdijk:

x32 is the x86_64 ABI that uses 32-bit pointers, so requires loading addresses into edi/esi/ebx rather than rdi/rsi/rbx.

Note that instructions such as movl %eax, (%rdi) do not require updating, as loading an address into %edi zeroes the high bits, causing the full %rdi register to hold a valid address.

Without this, even aplay segfaults when building with `-mx32`.
