From: Nishanth Menon <nm@xxxxxx>
Provide a quick set of access functions:
a) Convert omap_device to platform_device - This is the flip of
to_omap_device for equivalent usage
b) Convert omap_device to device pointer - This is useful for
most devices that need to go through standard linux functions that
take device pointer.
c) Convert hwmod to device pointer - This wrapper provides ability for
drivers to convert directly from hwmod name back to device pointer
without having to handle this on a driver by driver basis

[b-cousson@xxxxxx: Adapt it to the new pdev pointer inside od]
