The G3IPL expects the value at RAM address 0xa020b020 to be
exactly 1 to setup the bluetooth GPIOs properly. The actual
code got a value from gpio_get_value() which was not 1, but
a "not equal to 0" integer.

As requested by Ian make state restore only if it's requested
by platform data: some platforms do correctly save the state of
the chip during suspend/resume, but some (like tosa) incorrectly
power off the chip at suspend, so the driver supports restoring
some bits of the tc6393xb state (not full, merely enough to support
resume on tosa). With this patch this code is disabled by default.

The ISA IRQ renumbering broke the Viper ISA code in interesting ways.
It originally assumed that ISA interrupt were numbered in the order that
is defined by the CPLD registers. Unfortunately, this is no longer the
case.
Furthermore, the viper_irq_handler() function being a chained IRQ
handler, it must ACK the interrupt by itself, or the handler will be
immediately reentered, with the expected damages.
This fix was made possible thanks to the help of David Raeman, who
provided debug information and tested each version of this patch.

Most ARM machines don't need a special "DMA" memory zone, and
when configured out, the kernel becomes a bit smaller:
| text data bss dec hex filename
|3826182 102384 111700 4040266 3da64a vmlinux
|3823593 101616 111700 4036909 3d992d vmlinux.nodmazone
This is because the system now has only one zone total which effect is
to optimize away many conditionals in page allocation paths.
So let's configure this zone only on machines that need split zones.
