ENGR00233570-1 ASRC: Use hook to add support for ASRC loadable
ASoC ESAI machine driver and pcm platform driver use the APIs from mxc_asrc.c,
but once ASRC is used as a loadable module, these files can't find the APIs
from this ko. In this patch, we use 'asrc_p2p_hook' to hook the APIs which will
be used in ASoC ESAI machine driver and pcm platform driver.
