PATCH 1/1 OMAP: omap_device: replace pr_* prints with dev_*

For consistency in kernel printk output for devices, use dev_dbg(), dev_warn(), dev_err() instead of pr_debug(), pr_warning() and pr_err(), some of which currently use direct access of name from platform_device and others of which use dev_name(). Using the dev_* versions uses the standard device naming from the driver core.

Some pr_* prints were not converted with this patch since they are used before the platform_device and struct device are created so neither the dev_* prints or dev_name() is valid.

---
Unless there are objections, I'll queue this as a fix for the v3.1-rc cycle.

BTW, I tried applying this to today's linus/master, but it fails (rejects below), are you depending on some other changes ?

Oops, I forgot to mention it applies on top of a bunch of stuff queued for v3.1. Specifically, it's on top of Paul's prcm-devel-3.1 branch[1], which Arnd has merged into the arm-soc tree.

Patches to change that are welcome on the list.

It's not related to this patch which just changes from pr_warning to dev_warn, so needs to be done in a separate patch.
