[PATCH] cxl/mbox: Drop extra struct resource cast

[Jonathan Cameron <Jonathan.Cameron@huawei.com>]

DEFINE_RES_MEM() is a wrapper around the DEFINE_RES_NAMED()
macro which already has the (struct resource) cast.

Fixes warnings with W=1 C=1

I'm seeing a couple of other instances of this
drivers/acpi/arm64/gtdt.c
arch/arm/mach-shmobile/pm-rcar-gen2.c

Might get around to fixing them but more than happy if someone beats me to it.
