arch-arm: BadMode checking if corresponding EL is implemented

The old utility function called badMode was only checking if the mode
passed as an argument was a recognized mode. It was not checking if the
corresponding mode/EL was implemented. That function has been renamed to
unknownMode and a new badMode has been introduced.  This is used by the
cpsrWriteByInstruction function.  In this way any try to change the
execution mode won't succeed if the mode hasn't been implemented.
