[PATCH 5.10.y 1/6] kernel/params.c: Use kstrtobool() instead of strtobool()

[Sasha Levin <sashal@kernel.org>]

From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

[ Upstream commit def7b92efd868a6c78da86770704c1a03506016e ]

strtobool() is the same as kstrtobool().
However, the latter is more used within the kernel.

In order to remove strtobool() and slightly simplify kstrtox.h, switch to
the other function name.

While at it, include the corresponding header file (<linux/kstrtox.h>)
