Fix bug in flash driver where it could assert CS line after failing to claim
...
the bus. Also added a "claimed" flag to the device structure.

On revolution attach the flash chip to the accel bus now. Also extended the
...
flash chip driver to take in the slave number during initialization so this is
no longer a hardcoded option.

TO BE REVERTED: Temporary patch to make the w25x driver work with the revo m25p
...
chip. Need to abstract out the erase commands into a general pios_spi_flash
driver.

Remove all references to vTaskDelay in the flash code as it can run before the
...
FreeRTOS scheduler
Also increaes init stack size from 0x80 to 0x100

CC-15 Gets settings saved to flash chip on CC using crude sector based storage.
...
Sector based on Object ID so could overlap :-(.

CC-6 PIOS/SPI: Add semaphore to SPI device structure that can be used to ensure
...
only one CS line is asserted. No checks are enforced on this by the SPI code
as I cant see a clean way of it being aware of the CS lines. We could add
another CS mode those which is driver managed per transfer and has a GPIO i
line for each device.
