drm: omapdrm: Remove duplicate error messages when mapping memory
The devm_ioremap_resource() call can handle being given a NULL resource,
and prints an error message when mapping fails. Switch the remaining
devm_ioremap() calls to devm_ioremap_resource() and remove all
extraneous resource NULL checks and error messages printed manually by
the driver.
