1c2bfcff1e Implement Lan9730 powerycle for Exynos4 to make it attach; its not that 
trivial though as it relies on talking iic to the pmu and enabling lan_power
pin.

Some pins for the Odroid-XU boards have been added too.

4bbeac14dd Revisit gpio and revisit register file mapping. The additional register files 
are now mapped behind the origional register file.

The gpio channel GPZ is mapped over I2S0 in the separate audio register file
and were both abusively mapped over I2C0 in the main register file!

While here, delay the gpio bootstrap till on attachment. We could hasten it in
the odroid_machdep.c if needed. Also make the gpio code more resilliant and
allow booting correctly without any GPIO bits defined/available.

decendents. This allows post attach actions on every level of the machine

0c655d2ae4 Add the missing ETC0, ETC6, ETC7, ETC8 `gpio' registers. They are special in 
that they can't be set/unset nor configured. The only changeable parameters
are the pullups PUD and the DRV driving strength. They however fit the same
structure as the rest of the GPIOs and are used as such.

taken to allow for seamlessness adding of Exynos5 values.
