spidev_test: new package 



[Thomas: instead of building spidev_test directly from the source in
$(BR2_DL_DIR), use SPIDEV_TEST_EXTRACT_CMDS to copy the downloaded
source to the build directory, and build it from here. Allows to
manually tweak the source in the build directory for testing, allows
to apply patches over the source if needed, etc.]

	  SPI testing utility (using spidev driver).



	  This package builds and installs the userspace 'spidev_test'

	  command. It is up to the user to ensure that the kernel

	  configuration has all suitable options enabled to allow a

	  proper operation of 'spidev_test'.



	  The version used is based on your toolchain headers version,

	  if it's older than 3.15 then 3.0 is used, otherwise 3.15

	  is used.

	  This means you won't have quad-pumped SPI support if your

	  toolchain is too old.

# v3.15+ requires SPI_TX_QUAD/SPI_RX_QUAD to build

# Normally kernel headers can't be newer than kernel so switch based on that.

# If you need quad-pumped spi support you need to upgrade your toolchain.
