This patch adds support for enabling and configuring the engine on
VIAs IGPs. This is the main clock used for everything but pixel
output.

This patch introduces dummy functions to execute when we don't know
what we should do (due to missing documentation). They do nothing
but print a nice message in the log explaining the situation.
To trigger this message initial power management support is
activated which might save a bit energy by disabling PLL and clock
if no device is configured to use them.
Note: The message is only shown for the oldest IGPs CLE266 and K400
as for the other platforms there are reasonable assumptions
how it does (hopefully) work.

This patch is a huge move operation with some rename and introduces
an interface to still use the functions. This should be a step in
the right direction to reuse the code whenever possible but cleanly
separate code that differs on different platform and keeping the
complexity as low as possible.
pll_config was renamed to via_pll_config to keep the naming scheme.
