arm64: esr: Add ESR exception class encoding for trapped ERET

Browse source

The ESR.EC encoding of 0b011010 (0x1a) describes an exception generated
by an ERET, ERETAA or ERETAB instruction as a result of a nested
virtualisation trap to EL2.

Add an encoding for this EC and a string description so that we identify
it correctly if we take one unexpectedly.
