omap: rpmsg_resmgr: add support for regulators lookup
Support has been added to the machine-specific rpmsg resmgr layer
to retrieve and store the regulator data (defined in the board file).
A lookup_regulator op function is added to the mach-ops to retrieve
this data by the generic omap rpmsg resmgr layer based on the
regulator id.
