[PATCH v3 03/18] staging: hikey9xx: hisi-spmi-controller: clean sparse warnings

[Mauro Carvalho Chehab]

Sparse complains about __be32 conversions:

    drivers/spmi/hisi-spmi-controller.c drivers/spmi/hisi-spmi-controller.c:164:24:      warning: cast to restricted __be32
    drivers/spmi/hisi-spmi-controller.c drivers/spmi/hisi-spmi-controller.c:164:24:      warning: cast to restricted __be32

    drivers/spmi/hisi-spmi-controller.c drivers/spmi/hisi-spmi-controller.c:164:24:      warning: cast to restricted __be32
    drivers/spmi/hisi-spmi-controller.c drivers/spmi/hisi-spmi-controller.c:164:24:      warning: cast to restricted __be32
    drivers/spmi/hisi-spmi-controller.c drivers/spmi/hisi-spmi-controller.c:239:17:      warning: cast from restricted __be32

The conversions there are valid ones. So, add __force macro
to disable such warnings.
