Peter Griffin b45fd493da mfd: syscon: Add of_syscon_register_regmap() API 
[ Upstream commit 769cb63166 ]

The of_syscon_register_regmap() API allows an externally created regmap
to be registered with syscon. This regmap can then be returned to client
drivers using the syscon_regmap_lookup_by_phandle() APIs.

The API is used by platforms where mmio access to the syscon registers is
not possible, and a underlying soc driver like exynos-pmu provides a SoC
specific regmap that can issue a SMC or hypervisor call to write the
register.

This approach keeps the SoC complexities out of syscon, but allows common
drivers such as  syscon-poweroff, syscon-reboot and friends that are used
by many SoCs already to be re-used.
