-----------
core: Fix matching on mmio_region_unregister
Looking up the to-be-deleted region with zero legnth can cause false
matches:
Registered regions:
Start Size
0xb0000000 0x10000000
0x100000000 0x1000
0x100002000 0x20
0x100002020 0x20
Now trying to remove 0x100002020 will match on 0x100002000. This can be
trivially avoided by looking for a 1-byte region.
Fixes: 0993685e882f ("core: Add generic MMIO access dispatching")
