404ab21fe4 hv/trace_isp.py: add ISP tracer 
Image Signal Processor is a co-processor in charge of Facetime camera
in Apple laptops. This tracer is based on ISP found in M1 processor.

The ISP in M1 SoC exposes seven inter-process communication channels.
Using those channels Application Processor (AP) can perform a variety of
task in the ISP and viceversa. All channels seems to be bidirectional, with
unique exception of TERMINAL channel.

DART translation is used often to translate control structures passed
over IPC channels to IO virtual addresses.

How those channels are used is still unclear but tracer should allow us
to dive deep on high-level protocol to communicate with Facetime camera.
ISP exposes also some I2C peripheral and SPMI registers but I haven't
dive into their working or purpose.

21dc622735 kboot: Transfer display related memory carveouts to device tree 
DCP and disp0 need their bootloader iommu mappings maintained until
an OS driver can take over. DCP's mappings have to be kept
indefinitively since it's unknown if or how it can be restarted.

2e1ed1d457 nvme: Increase enable timeout to 5s, do a clean shutdown on fail 
It seems unclean startup sometimes takes longer. On top of that, if we
don't do a clean shutdown in the error path, the next startup will
continue failing (we know hard-disable triggers races and crashes the
ASC).
