* [PATCH] ASoC: txx9: add back the hack for a too small resource_size_t

Looks like I misread the Kconfig magic and this driver can be compiled
into 32-bit kernels.  Add back the hack to extent the range of the
resource_size_t, and include the header with the txx9-specific ioremap
magic for that.

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea.                                                [ RFC1925, 2.3 ]
