ASoC: pcm: Add support for compat mode

When kernel is compiled for 64 bit and userspace client
is in 32 bit mode compat ioctl path will be taken. If
platform driver supports compat mode asoc framework
should call compat function pointers.
Change adds support in asoc framework to support compat mode.
