[PATCH] nvidiafb: Fix mode setting & PPC support

This patch fixes nvifiafb mode setting code to be closer to what the X
driver does, which actually makes it work on the 5200FX I have access to.
It also fix the routine that gets the EDID from Open Firmware on PPC, it
was broken in various ways and would crash at boot.  Compared to the patch
I posted to linux-fbdev last week, this one just changes a printk to be
closer to the other ones in the driver.
