sparc64: Add ADI capability to cpu capabilities

Browse Source 
Add ADI (Application Data Integrity) capability to cpu capabilities list.
ADI capability allows virtual addresses to be encoded with a tag in
bits 63-60. This tag serves as an access control key for the regions
of virtual address with ADI enabled and a key set on them. Hypervisor
encodes this capability as "adp" in "hwcap-list" property in machine
description.
