Consolidate log commands so that dev_info(NULL, "Error...") uses the more
accurate pr_err, remove the module name from the log (can be seen via
dynamic debugging with +m), and the function name (can be seen via

what function we're in. Those can be added by devs when needed

Don't print vendor and device ID in error messages. They are typically

The omapdrm platform device is a virtual device created for the sole
purpose of handling the omapdss/omapdrm driver split. It should
eventually be removed. As a first step to ease refactoring move its
registration from platform code to driver code.

The omapdrm driver name must be changed internally to avoid probing both
the device registered in platform code and the device registered in the
omapdss driver, as that would otherwise break bisection.
