1ea31ae996 dart: Add setup of pre-allocated L2 tables for dcp/disp0
DART nodes for dcp and disp0 have pre-allocated L1 and L2 tables which
are annotated in the ADT. The pre-allocated memory is specified in
"pt-region-${DEVICE}". The first page is used as L1 table and the
following pages are used as L2 tables. The number of valid L2 tables is
specified in "l2-tt-${DEVICE}". The first entry identifies the region
and the second entry is the number of valid L2 tables.

iboot (macOS 12.3) inits just 2 L2 tables. Larger framebuffers require
more. By using the pre-allocated page tables we do not have worry about
keeping the memory mapped after m1n1 executes the next target.

c577e94d75 display: limit timing modes by framebuffer size
The reserved framebuffer on the Mac Studio is 0x854000 bytes. This is
too small for 1920x1200 with 4 byte per pixel. Setting 1920x1200 as
mode crashes dcp but not the actual display controller. The display
remains working and even comes back after display hotplug/power cycle.

8eeb7966aa hv: Refactor CPU switch logic, make hv.cpu() not exit shell
Get rid of the hv_rearm() thing (which was always a bit dodgy) and
instead properly make sure that all CPUs rendezvous when needed and
switch the active proxy thread without ever exiting exception context.

The Python side can now switch proxy context (by waiting directly for
a proxy boot) without having to exit out of the hypervisor callback,
so cpu() now works as a normal Python method.

Add a cpus() iterator so you can do things like:

>>> for i in cpus(): bt()
