[PATCH v3 1/8] spi: spidev_test: include tools/include

[Jonas Rebmann]

Add tools/include to include paths to allow using macro helpers.

Use ARRAY_SIZE() from tools/include/linux/kernel.h instead of
maintaining a copy.

Remove the obsolete comment with cross-compile instructions from the
header since spidev_test is integrated with the tools buildsystem since
commit f325b73dc4db ("spi: tools: move to tools buildsystem").
