arch-arm: don't expose FEAT_VHE by default
If FEAT_VHE is implemented and Linux boots in EL2, it programs itself
to operate in EL2. This causes a later boot stall as explained in
https://gem5.atlassian.net/browse/GEM5-901.
We provide a parameter "have_vhe" to enable FEAT_VHE on demand. This is
disabled by default until fixed. This avoids users stalling on the common
case of booting Linux without a hypervisor.
