linux: Adapt servo0 channels for beagleboard kernel 4.14.108-ti (#2746) 
The beagleboard TI kernel 4.14 and 4.19 contain a commit which change
the device names ("pwm: Create device class for pwm channels") from
pwmN to pwm-${chip}:N. This commit was never merged into the upstream
kernel.

Decrease the number of pwm channels to a more reasonable 16. Increase
the number of pwm chips to 8 since the replicape servo pwm outputs are
on pwmchip4.

Update replicape code to detect appropriate channel.

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].

Kevin O'Connor 8532e2123e gpiocmds: Specify soft pwm duration in clock ticks 
Improve the precision of soft pwm pulses by allowing the host to
directly specify the clock duration of the pulse.  This improvement in
precision may be noticeable when controller servos (and bltouch).

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.
