hw/arm/smmuv3: Support HAD and advertise SMMUv3.1 support

Browse source 
HAD is a mandatory features with SMMUv3.1 if S1P is set, which is
our case. Other 3.1 mandatory features come with S2P which we don't
have.

So let's support HAD and advertise SMMUv3.1 support in AIDR.

HAD support allows the CD to disable hierarchical attributes, ie.
if the HAD0/1 bit is set, the APTable field of table descriptors
walked through TTB0/1 is ignored.
