Kevin O'Connor 121249c999 stm32: Revert "stm32: performance improvement for spi on stm32f0" 
This reverts commit a2c309a2b0.

The above commit is causing crashes on the stm32f103xb chip when spi
is in use.  It's unclear what the cause of the regression is, but the
optimization isn't required so revert it until the root cause can be
determined.

Arne Jansen a2c309a2b0 stm32: performance improvement for spi on stm32f0 
The stm32 has a small queue for spi tx/rx. The current code only uses the
spi with a single byte buffer, effectively waiting for each byte to complete
before starting the next transfer.
This patch changes the structure of spi_transfer() to make use of the queue
and achieve back-to-back transfer of bytes on spi.

Arne Jansen ce35ee45d6 stm32: fix spi_transfer for stm32f0 
The current code accesses the DR as 32 bit. This enabled data packing mode,
effectively adding a 00 byte between each sent byte. The receive side had
similar problems.
To prevent this, all accesses are 8 bit now, even though this is not
necessary on stmf[14].

Janne Grunau aab89e7f85 linux: add support for Linux hardware PWM 
The replicape servo pins (P9_14/P9_16) are muxed to the SOCs hardware
PWM unit driven by a 13MHz GP timer. They have to be driven by the
linux host mcu. This commits adds hardware PWM support using the linux
sysfs user space interface.

Kevin O'Connor 55df8bf55f armcm_timer: Add a generic timer mechanism for ARM CortexM3/M4 chips 
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.

Kevin O'Connor e26d1a3567 i2ccmds: Pass the i2c address as a 7-bit number (0-127) 
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.
