This patch removes all internal uses of another mostly artificial
value. It does duplicate the information of the maximum resolution and
it is not flexible as only a few resolutions exist. Hence it is better
to remove it and clean the mess up.
No runtime change expected.

This patch merges tbl1636 into vt1636 and cleans it up as the data was
only used there anyway. No runtime changes are expected.

This patch moves common parts of dvi.c, lcd.c and vt1636.c to hw.c to
start a per output device power management. There should be no runtime
changes aside that this patch enables the proc interface to enable/disable
devices when needed which greatly increases the chances that changes to
the output device configuration will work. However the power management is
not yet complete so it might fail on some configurations. As this area is
quite complex and touches undocumented things there is a slight chance of
regressions.

The code was ugly and didn't check whether i2c operations were succeeding;
make it a little better.

This patch moves data of interest into a new viafb_dev structure which
describes the device as a whole; the idea here is to create a separation
between what all devices may need and what the framebuffer device in
particular needs.
I've also made some small steps toward thinning out the global.h mess.

This patch changes the way how the various I2C busses are used internally
inside the viafb driver: Previosuly, only a single i2c_adapter was created,
even though two different hardware I2C busses are accessed: A structure member
in a global variable was modified to indicate the bus to be used.
Now, all existing hardware busses are registered with the i2c core, and the
viafb_i2c_{read,write}byte[s]() function take the adapter number as function
call parameter, rather than referring to the global structure member.

This patch introduces viafb_shared and is the beginning of a smooth
transition to use it.
viafb_shared should contain all general, non-surface specific data that
should be shared along all viafb framebuffers while viafb_par should only
contain things that are specific to each surface or in other words extend
fb_info. This change is intended to clean the dual/multi framebuffer
handling up.
This removes the annoyance that viafbinfo1->par points to a different
structure than viaparinfo1.
As the last change is fundamental it is difficult to ensure that all parts
of the driver do not depend on the previous brokenness but the chance of
regressions is very low.
