Kevin O'Connor c2a08962b7 spicmds: Rework spi config commands 
Rework the spi_config commands so that bus configuration and shutdown
message configuration is done separately from the main "config_spi"
command.  This makes the spi configuration more flexible.  It's now
possible to use software spi without a CS pin.  It's now possible to
define multiple SPI messages to send on a shutdown event.

The ARM CortexM3 (and later) chips almost always have a 32bit timer in
the "Debug and Watch Trace" (DWT) unit which resides within the cpu
core itself.  This timer is generally faster to access than timers
located on the chip's peripheral bus.  When combined with the standard
ARM SysTick timer it provides a (generally) portable mechanism to
implement Klipper's software timer mechanism.  It's generally also
faster than using the vendor specific timers.

The sam3 i2c code and the linux code use a 7-bit i2c address, while
the avr, lpc176x, and samd21 i2c code uses an 8-bit address with the
least significant bit always zero.  A similar issue occurred in the
host code (sx1509.py and replicape.py use 7-bit addresses while
uc1701.py and mcp4451.py use 8-bit addresses).

Consistently use 7-bit addresses in all the code.  This breaks
compatibility between host and mcu software, so make a change to the
config_i2c command to force users to synchronize software updates.
This also breaks common Smoothieboard configs, so update the mcp4451
code to validate the i2c_address.

move the twi pin definitions from internal.h to i2c.c (as they are only
used there).
