[ Upstream commit 49dc762c ]

The driver should really call dm365_isif_setup_pinmux() through a callback,
but uses a hack to include a davinci specific machine header file when
compile testing instead. This works almost everywhere, but not on the
ARM omap1 platform, which has another header named mach/mux.h. This
causes a build failure:

Exclude omap1 from compile-testing, under the assumption that all others
still work.
