l2x0_init() allows to overwrite bits in the AUX_CTRL register
using the aux_val/aux_mask arguments. On i.MX35 this is used
to pass a correct AUX_CTRL value to overwrite bogus reset values
for this register. To make this work we have to apply
aux_val/aux_mask before using the AUX_CTRL value to determine the
way size.

This fixes: 3f7e890da7 ARM: l2x0: Implement L310 support
Before this commit the way size was hardcoded to 8.

There are systems like the Calxeda Highbank, which need to do SMC
calls in order to access the secure L2C registers, which means they
want to replace the outer cache disable function with their own.

As the cache flush before entering the boot target is still needed
and to avoid exposing L2C internals to the architectures move the
flush before disable into the only current user.

Otherwise entries may still be in the cache and never reach memory.

To allow for some generic io accessors introduce io.h and use
this instead of asm/io.h throughout the tree.
