ASoC: Update config of SND_HWDEP

As CONFIG_SND_HWDEP is defined by default
in kernel tree, msm-pcm-routing-devdep.c file
in audio drivers gets compiled always.
kernel 4.9 is now enabled with 8953 compilation,
and result in failure on audio drivers component 1.0
due to above file.
Audio drivers component 2.0 is used for 8953 support,
but kernel 4.9 is common for audio drivers 1.0 and 2.0.
To fix above compilation issue, use CONFIG_SND_HWDEP_ROUTING
config instead of CONFIG_SND_HWDEP to compile
msm-pcm-routing-devdep.c file.
