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.

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 bbf6f87de0 avr: List 20Mhz option below 16Mhz option in Kconfig 
When enabling "low level options" in Kconfig, selecting a chip that is
20Mhz capable would result in 20Mhz being the default.  A 16Mhz speed
is the preferred default, so list that first in the menu.
