a9088e2278 fb: Add the ability to defer FB console activation 
This differs from removing the IODEV usage in that console contents
are still buffered.

26f636dbbb fb: Use 128-bitwise copies to speed up FB updates 
This makes it almost as fast as it was before the switch to an
uncached framebuffer, as far as I can tell.

8fa422c0d3 fb: Map the framebuffer uncached, and use a shadow FB for speed 
Turns out AMCC on t600x throws errors when DISP0 real-time memory
requests hit the CPU cache, and then macOS panics.

da024ffbd8 memory: Only map available RAM 
We saw some crazy speculation running in the HV breaking things by
reading from invalid RAM, so let's actually map only what's available.
For now we do map all lowmem as we haven't seen SErrors there yet, but
we stop at the high boundary.

Fixes: #97

Also don't clear the whole screen, only the console section so the logo

clang-format is supposed to do this, but for some reason it's "sticky"
and doesn't...

cc4a5d312d iodev: Add new framework for I/O and console devices

d63e84d2f7 fb: add fb_console_reserve_lines() 
This is like fb_console_scroll(), but only scrolls if necessary to
ensure that enough free space is available at the end of the console.
This avoids spuriously scrolling during shutdown if we still have space.
