H A Dutility.hhdiff 14169:7b419cdddf0a Thu Aug 15 08:27:00 EDT 2019 Giacomo Travaglini <giacomo.travaglini@arm.com> arch-arm: Rewrite the currEL helper method to use opModeToEL

Direct use of cpsr.el should be discouraged: it should be used when
in AArch64 only; when in AArch32 it won't return the matching EL.

Eg: when in Supervisor Mode (EL1), CPSR.M<3,0> (mode) is 0b0011,
and cpsr.el will return 0 (EL0)
