Subject[PATCH 12/12] docs: kernel-parameters.txt: remove reference for removed Intel MPX
The Intel MPX support got removed on Kernel 5.6, but the
kernel-parameters file still mentions it.

Update the text to document that this parameter is not needed
anymore, as the Intel MPX will always be disabled now on
(as its support got removed).
