VA spaces have no valid PA addresses stored in memory map, so they are
not valid return values for core_mmu_get_type_by_pa() function.
This issues was discovered when OP-TEE tried to access a device tree
that was stored at the very beginning of physical address space. In
may case it had PA address 0x112C0, which was "covered" by
RES_VASPACE:
D/TC:0 0 dump_mmap_table:838 type RES_VASPACE va 0x1d800000..0x1e1fffff pa 0x00000000..0x009fffff size 0x00a00000 (pgdir)
