Peter Maydell a23e719ca8 target/arm: Don't set HCR.RW for AArch32 only CPUs 
In commit 39ec3fc030 we fixed a bug where we were not implementing
HCR_EL2.RW as RAO/WI for CPUs where EL1 doesn't support AArch32.
However, we got the condition wrong, so we now set this bit even on
CPUs which have no AArch64 support at all.  This is wrong because the
AArch32 HCR register defines this bit as RES0.

Correct the condition we use for forcing HCR_RW to be set.
