[PATCH 5.10.y 2/4] platform/x86: Rename hp-wireless to wireless-hotkey

[Sasha Levin <sashal@kernel.org>]

From: Mario Limonciello <mario.limonciello@amd.com>

[ Upstream commit a558ea42c0decd088df1950bb232ac2257929281 ]

This driver was originally intended to support some HP laptops, but
later support was added for Xioami and AMD laptops.

Rename it to make it clear that it supports a larger variety of
systems.
