[Sound-open-firmware] [PATCH 3/3] configure.ac: add CONFIG_HOST_PTABLE flag for platforms which need handle it

[Keyon Jie]

We only need handle host page tables on platforms that we
program DMA host buffer(addr/size) inside firmware, for
other platforms, host driver will program these settings
and won't pass in page tables.

So here add frag CONFIG_HOST_PTABLE to configure this for
different platforms, on Baytrail, Cherrytrail, we need
CONFIG_HOST_PTABLE to be selected.
