d2956e4044 kboot: Add mapped reserved-memory ranges to memory map 
This is the same thing U-Boot does for the EFI mem map, and means these
ranges get a `struct page` in the kernel.

55efddda71 kboot_gpu: Do not set no-map prop on reserved-memory nodes 
This is set in the device trees anyway, but a future kernel release may
rely on this being *not* set.

8508526515 display: contain all display init logic within display.c 
Display handling was spread across main.c, utils.c and display.c
with the addition of iDevice support. Condense all of this functionality
into display.c.

This also fixes a regression introduced in 869d2ae35c ("Skip over features
unsupported in A7-A11 SoCs."), which caused devices using dcpext to skip DCP
initialisation.
