Previously the maximum number of deferred routines was specified by the
the default maximum number of deferred routines you had to override
this, and if you wanted fewer, you still payed the price of having the
defer_until array statically allocated to be the maximum size.
This change removes that define and instead creates the RAM state of
the deferred routine (the time to wait until to call the deferred) when
the deferred is declared.

There are hooks for chipset power sequencing but not one to indicate
that the system has reset at runtime. Add a hook for this and
implement for lm4 and mec1322. The hook is notified on any platform
reset, including those that happen on the way into S3/S5 state.
There is a new config variable added because the hook is notified in
the interrupt handler and needs a deferrable function that needs to
be added to every board.

This patch introduces a facility which would allow to compile in
callbacks for arbitrary commands passed over various communication
protocols.
Typically this will be used for testing, when various test commands
are multiplexed over an existing protocol.
The callbacks are associated with 16 bit command codes. On input the
callback receives a buffer, containing the command's argument, the
size of the command argument and the maximum size of the buffer. On
output the callback stores processing result in the same buffer and
updates the size to the actual amount of returned data.
Callback descriptors are stored in a dedicated read only section which
is scanned by extension_route_command() to find a callback associated
with a certain command code.
A console channel is also being introduced to allow controlling
console output generated by extension commands handlers.

The memcpy like routines for moving to and from usb packet
RAM couldn't deal with all unaligned uses, this fixes their
behavior. In particular, a previous caller might assume
that the packet RAM addresses were contiguous and attempt
to break up a call into two separate chunks (as the queue
insertion/removal code does). But this can lead to invalid
pointers passed to these memcpy routines. A much cleaner
solution is to make the packet RAM address space contiguous.
To do so the memcpy routines take packet RAM addresses
instead of AHB address space mapped addresses and
__usb_ram_start needed to change to be of type usb_uint so
that pointer arithmatic on it worked correctly on all platforms,
this also allowed the usb_sram_addr macro to be simplified.

Before this change drivers had no way of knowing that a frequency
change was coming. This could cause problems for some drivers (like
i2c) that need to make sure that a transaction isn't happening while a
frequency change is happening.
The PRE_FREQ_CHANGE archiecture is very simple here and we don't allow
any way to cancel it.
At the moment, we guarantee:
- We won't call PRE_FREQ_CHANGE with interrupts disabled, so acquiring
locks / sleeping is OK.
- We'll call the actual HOOK_FREQ_CHANGE after the PRE_FREQ_CHANGE.
PRE_FREQ_CHANGE and HOOK_FREQ_CHANGE should not use deferred function
calls.
