[PATCH 3/8] Documentation: add ARM user_debug to kernel-parameters.txt

[Randy Dunlap <rdunlap@xenotime.net>]

From: Stephen Boyd <sboyd@codeaurora.org>

Usually kernel parameters are documented in kernel-parameters.txt
but user_debug is only documented in the Kconfig. Document the
option and point to the Kconfig help text for more info.
