Don't make assumptions about usable memory.
...
When using a legacy BIOS, the memory regions used by the BIOS are well
defined. This is not the case when using a UEFI BIOS. So include the
stack area in the BSS so the loader knows how much memory to allocate,
and check we have space to relocate the program to either low or high
memory.
There are still some assumptions in the USB driver code that need to
be fixed.

Add support for USB hubs.
...
This refactors the USB driver code into a more object-oriented design,
with usbkbd.c being the base class and ohci.c and xhci.c being subclasses.
This makes the code that performs USB device enumeration independent of
the host controller.

Flush caches between writing and verifying test data.
...
Mostly we write and read large chunks of data which will make it likely
that the data is no longer in the cache when we come to verify it. But
this is not always true, and in any case, we shouldn't rely on it.
