pcm: dmic: assembly: add x32 support.

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.
