Add imx8qxp lpcg driver support

Cc: Stephen Boyd <sboyd@kernel.org>
Cc: Shawn Guo <shawnguo@kernel.org>
Cc: Sascha Hauer <kernel@pengutronix.de>
Cc: Fabio Estevam <fabio.estevam@nxp.com>

ChangeLog:
v11->v12:
 * remove dependency of CONFIG_SOC_IMX8QXP which will be deleted later
v7->v11:
 * no changes
v6->v7:
 * use resource_size()
 * add kernel doc for structs
 * Include this after <linux/*> and before locals
 * remove MODULE_ macros
 * add suppress_bind_attrs
v6:
 * new patch, separate from scu gate driver
