Before this we suppress all ARM_CP_NORAW registers being listed under
GDB. This includes useful registers like CurrentEL which gets tagged
as ARM_CP_NO_RAW because it is one of the ARM_CP_SPECIAL_MASK
registers. These are registers TCG can directly compute because we
have the information at compile time but until now with no readfn.
Add a .readfn to return the CurrentEL and then loosen the restrictions
in arm_register_sysreg_for_feature to allow ARM_CP_NORAW registers to
be read if there is a readfn available.

up-streaming. See thread comments for details.
