[igt-dev] [PATCH i-g-t v3 4/4] testplan/meson.build: cleanup dependency chain

[Mauro Carvalho Chehab <mauro.chehab@linux.intel.com>]

From: Mauro Carvalho Chehab <mchehab@kernel.org>

Simplify the checks inside testplan/meson.build and ensure that
it will only build if option build_testplan is selected, by moving
such check to docs/meson.build.

Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
