Commit 185bae1095188aa199c9be64d6030d8dbfc65e0a ("OMAPDSS: DSS: Cleanup
cpu_is_xxxx checks") broke the DSS clocks configuration by erroneously
using the clock parameters applicable to all other OMAP34xx SoCs for the
OMAP363x. This went unnoticed probably because the cpu_is_omap34xx()
class check wasn't seen as matching the OMAP363x subclass.

Fix it by checking for the OMAP363x subclass before checking for the
OMAP34xx class.

Hi Tomi,

The patch has been tested on the Beagleboard-xM and restores the DVI output
operation. This is a regression fix that should be pushed to v3.7.

Good catch, thanks. I don't have a 36xx board, so this went unnoticed.
I'll push it for 3.7-rc.
