d4b3e758da display: trigger dptx hpd before waiting for iboot hpd 
This is not enough to make the display work but at least triggers
dptx-phy link config (lane count/link rate).

display.

f1664ccef4 dart: Add DART_PTR_ERR to indicate failures for IOVA returning functions 
0 is a valid and used device virtual address. Daart functions returning
device address can not use 0 to indicate errors.

714420a694 display: Put DCP to sleep if display is external 
This stops DCP from killing our modeset if the connection cycles.

Also force a (potential) configure cycle if the display is external;
this makes sure updated stage2s will have a chance at fixing issues of
old stage1s. Modesetting is fast when it's the same mode as before.

7f4347ebe8 display: Reallocate framebuffer if required for wanted display mode 
If an explicitly specified display mode exceeds the allocated
framebuffer allocate a new one from the top of RAM.

Note: macOS panics immediately with a realloced framebuffer.

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.

1b5dee2496 display: Map the framebuffer if it is not mapped
