target-arm: Fix wrong AArch64 entry offset for EL2/EL3 target 
The entry offset when taking an exception to AArch64 from a lower
exception level may be 0x400 or 0x600. 0x400 is used if the
implemented exception level immediately lower than the target level
is using AArch64, and 0x600 if it is using AArch32. We were
incorrectly implementing this as checking the exception level
that the exception was taken from. (The two can be different if
for example we take an exception from EL0 to AArch64 EL3; we should
in this case be checking EL2 if EL2 is implemented, and EL1 if
EL2 is not implemented.)
