target/ppc: add LPCR[HR] to DisasContext and hflags
Add a Host Radix field (hr) in DisasContext with LPCR[HR] value to allow
us to decide between Radix and HPT while validating instructions
arguments. Note that PowerISA v3.1 does not require LPCR[HR] and PATE.HR
to match if the thread is in ultravisor/hypervisor real addressing mode,
so ctx->hr may be invalid if ctx->hv and ctx->dr are set.
