Remove the cursor timer (cursor flashing) on the following conditions:
- if vc is in KD_GRAPHICS mode, ie, when X owns the console
- if vc is blanked

Every time the console cursor blinks, we do a kmalloc/kfree pair. This
patch turns that into a single allocation.
This allocation was the most frequent kmalloc I saw on my test box.

- separate from fbmon.c and place in new file fb_ddc.c
- remove dependency to CONFIG_I2C and CONFIG_I2C_ALGOBIT, otherwise, feature
will not compile if i2c support is compiled as a module

Convert LOMOMO to use struct device * for GPIOs instead of struct
locomo_dev. This enables access to the GPIOs from code which is not
a locomo device itself (such as audio). Access for gpio 31 is removed
for error handling (no such hardware exists).

The backlight changes that went in had a bug where they could cause the
kernel to access an unitialized pointer when blanking if there is no
backlight control on a machine.

be ok. This fixes it.

I wish I was happier about this patch. It'll serve as a placeholder for
the moment. I'm still trying to get a G550 working in order to even
reproduce the problem this patch introduces. I find that the G450 has
jitter even without this patch, so it won't show me what the patch changed.
At this point, I'll continue trying to get the G550 to work, and in
parallel work with the G450 to work out the kinks.
The patch is below.
Set XDVICLKCTRL only on PPC, as doing this apparently introduces jitter on
the G550, at least on x86 architectures.
