Maybe better if you add nGRE too and no capture group using (?:...)$

FYI: These appear unused to date:

$ git grep FFA_DEV
include/linux/arm_ffa.h:#define FFA_DEV_nGnRnE          (0 << 2)
include/linux/arm_ffa.h:#define FFA_DEV_nGnRE           (1 << 2)
include/linux/arm_ffa.h:#define FFA_DEV_nGRE            (2 << 2)
include/linux/arm_ffa.h:#define FFA_DEV_GRE             (3 << 2)
