[PATCH v2 20/24] docs: kernel_include.py: remove line numbers from parsed-literal

[Mauro Carvalho Chehab <mchehab+huawei@kernel.org>]

When parsed-literal directive is added to rawtext, while cross
references will be properly displayed, Sphinx will ignore
line numbers. So, it is not worth adding them.
