Relaxed I/O accessors for `Mmio` are currently implemented as an extra

why:
Workaround for duplicate cursor. Cursor offsetting via x_hotspot attempts
to write a 32 bit unsigned integer to the 8 bit field CURSOR_HOT_SPOT_X.
This wraps cursor position back into focus if x_hotspot exceeds 8 bits,
making duplicate cursors visible
how:
Clamp x_hotspot before writing to hardwa... | ```diff

mb_cache_destroy() calls shrinker_free() and then frees all cache
entries and the cache itself, but it does not cancel the pending
