This patch adds a tty driver to the PDC console. It allows the use
of ports not supported by linux as a console (e.g. serial port on
C8000.) The tty driver will not register the ttyB device if PDC console
driver has been unregistered. This happens when the early printk
console is disabled as it has not been selected as the primary console.

The APB DMA block handles DMA transfers to and from some peripherals
in the Tegra SOC. It reads from sequential addresses on the memory
bus, and writes repeatedly to the same address on the APB bus.
Two transfer modes are supported, oneshot for transferring a known
size to or from a peripheral, and continuous for streaming data.
In continuous mode, a callback occurs when the buffer is half full
to allow the existing data to be handled and a new request queued.x

Having many dozens of modules, the searches down the linked
list of sections would dominate the lookup time, dwarfing
any savings from the binary search within the section.
A simple move-to-front optimisation exploits the commonality
of the code paths taken, and in simple real-world tests
on other architectures reduced the number of steps in the
search to barely more than 1.

- the reset values for some pin groups in the tegra pin mux can result in
functional errors due to conflicting with actively-configured pin groups
muxing from the same controller. this change adds a known safe, non-
conflicting mux for every pin group, which can be used on platforms
where the pin group is not routed to any peripheral
- also add each pin group's I/O voltage rail, to enable platform code to
map from the pin groups used by each interface to the regulators used
for dynamic voltage control
- add routines to individually configure the tristate, pin mux and pull-
ups for a pingroup_config array, so that it is possible to program
individual values at run-time without modifying other values.
this allows driver power-management code to reprogram individual
interfaces into lower power states during idle / suspend, or to
reprogram the pin mux to support multiple physical busses per
internal controller (e.g., sharing a single I2C or SPI controller
across multiple pin groups)
- move chip-specific data like pingroups and drive-pingroups
out of the common code and into chip-specific code
- fix debug output for group with no pullups
- add a TEGRA_MUX_SAFE function. Setting a pingroup to TEGRA_MUX_SAFE
will automatically select a mux setting that is guaranteed not to
conflict with any of the hardware blocks.

"wait" this allows the caller to specify if it wants to stop until all

for the kexec case where we should wait for all the cpus to be stopped
before starting the new kernel. We now wait for the cpus to stop in
all cases except for panic/kdump where we expect things to be broken
and we are doing our best to make things work anyway.
