ASoC: DaVinci EVM board support buildfixes

This is a build fix, resyncing the DaVinci EVM ASoC board code
with the version in the DaVinci tree.  That resync includes
support for the DM355 EVM, although that board isn't yet in
mainline.

(NOTE:  also includes a bugfix to the platform_add_resources
call, recently sent by Chaithrika U S <chaithrika@ti.com> but
not yet merged into the DaVinci tree.)
