target/arm: Fix S1_ptw_translate() debug path
In commit fe4a5472ccd6 we rearranged the logic in S1_ptw_translate()
so that the debug-access "call get_phys_addr_*" codepath is used both
when S1 is doing ptw reads from stage 2 and when it is doing ptw
reads from physical memory.  However, we didn't update the
calculation of s2ptw->in_space and s2ptw->in_secure to account for
the "ptw reads from physical memory" case.  This meant that debug
accesses when in Secure state broke.

Create a new function S2_security_space() which returns the
correct security space to use for the ptw load, and use it to
determine the correct .in_secure and .in_space fields for the
stage 2 lookup for the ptw load.
