Subject: [PATCH 3/8] mailbox: Kconfig: enable ARM SMC mailbox on 64-bit Allwinner SoCs

For 64-bit Allwinner SoCs there exist firmware implementations which
provide SCPI controlled handlers for DVFS, sensors and power domains.
To allow usage of this features, enable the required SMC mailbox when
Allwinner SoCs are supported by the kernel.
