Lucas De Marchi 27dafa8f1b AP_HAL_Linux: remove state leftover from SPIDeviceDriver
This was previously used to allow to save a state in a SPIDriver so we
could synchronize the initialization of AP_Compass and
AP_InertialSensor.

It was only used by MPU9250 and is not used anymore since the move to
AuxiliaryBus initialization and it's not used anymore since c3dae6f

Lucas De Marchi 2439826c19 AP_HAL_Linux: use init() method without arguments
Override the init() method from parent class that doesn't have a
parameter since it's not used here.

Lucas De Marchi 2ac96b942c AP_HAL_Linux: remove prefix from AP_HAL_Linux classes
We have already a Linux namespace, so there's no need to prefix Linux on
all names.

Gustavo Jose de Sousa 124b750c10 AP_HAL_Linux: standardize inclusion of libaries headers
This commit changes the way libraries headers are included in source files:

 - If the header is in the same directory the source belongs to, so the
 notation '#include ""' is used with the path relative to the directory
 containing the source.

 - If the header is outside the directory containing the source, then we use
 the notation '#include <>' with the path relative to libraries folder.

Some of the advantages of such approach:

 - Only one search path for libraries headers.

 - OSs like Windows may have a better lookup time.

Lucas De Marchi fde43a77b3 AP_HAL_Linux: allow to change spi device state
Allowing to change the SPI device state allows us to save the
information whether the device was already initialized and avoid 2
separate drivers to initialize it.

Lucas De Marchi b211b86204 AP_HAL_Linux: don't manually define number of spi devices
It's error-prone, let's make the compiler define it for us.

John Williams 0fe3959d7e AP_HAL_Linux: Add support for in-kernel SPI CS handling
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

Andrew Tridgell a46d8dbd51 HAL_Linux: make the spi driver fd part of the manager, not device

Andrew Tridgell d0b007248f HAL_Linux: fixed SPI semaphore, and panic on CS error
This adds a check for trying to assert two CS pins on the same bus
at the same time. The change involves moving the _device handles into the
DeviceManager class, and accessing via static methods.

This also moves the semaphore to be per-bus rather than per-device,
which fixes the problem with bad MS5611 transfers.
