xlat: Define translation regime in AArch32 

Previously, in AArch32, `IMAGE_XLAT_DEFAULT_REGIME` wasn't defined. The
translation regime is only used in the AArch64 port of the translation
tables library v2, so this is not a problem for now, but future patches
will use it.

`IMAGE_EL` isn't used in AArch32, so it isn't needed to define it.
