Add support for /dev/spidev<bus>.<cs> in-kernel SPI CS handling, and convert
existing SPI devices over.
* Add a new member _subdev to the LinuxSPIDeviceDriver class, and initialiser
in LinuxSPIDevice constructor. Use subdev 0 for GPIO-managed CS
* Extend the _cs_pin to signed 16 bits and define SPI_CS_KERNEL (-1) for
kernel-managed CS
* Move to per-device file descriptors (required for in-kernel CS)
* Extend spidev filenames to include bus and subdevice numbers, possibly
longer than 1 digit each
* Allow support for platforms enumerating /dev/spidevNNN from non-zero bases
* Convert existing users over to the new API

ToneAlarm is now declared as a separate class instance of which is added as a private member of LinuxUtil
Some minor fixes in this patch include changing return type of tonealarm_init() to bool and use dprintf
exit from the autpilot when reboot is commanded.
The software assumes that the code is being
launched in an infinite loop thereby an exit
will make it reboot.
Preliminary support for Zynq/Linux on the 'ZyboPilot' HW platform.
see https://github.com/trjw/ZyboPilot-bsp for the PetaLinux / Vivado project
files.
At this stage CPPM/Pulse in and PWM out work, and in CLI mode the passthru
test works correctly.
The platform has passed minimal smoke testing in HIL mode.
ZYNQ IS NOT FLIGHT TESTED YET! FLY THIS PLATFORM AT YOUR OWN RISK!

Forthcoming Zynq port AP_HAL_Linux uses similar constants with different
values - move these as private member constants to avoid collisions.

When a S.Bus signal is fed into the rcin-Pin AruPlane on the BBB get's a
Segmentation fault. This patch prevents the memory acces to dsm_state.bytes[16] outside
of the array bounds. The patch should be reviewed by sombody who knows the DSM protocol,
as i don't.
