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.

6765bc3ff6 hv_vm: Support >36-bit PAs
This needs an extra L1 translation level, but only on SoCs with support
for >36-bit PAs. On M1, we bypass it and keep starting at L2.

b15be6bcd7 Remove hardcoded UART/WDT addresses
The M1 Pro/Max Macs use a different base address for the UART and the
WDT than earlier models.

Remove hardcoded base addresses constants and replace them with loads
from the ADT.

- The base address of the WDT is already retrieved in wdt_disable; also
use this address when triggering a reboot.
- Retrieve the base address of uart0 in uart_init. If the operation
fails, the error will be signaled on the early uart (if not disabled).
- The early debug UART can’t use the ADT (or shouldn’t) so it is now
disabled by default. To enable it, add
-DEARLY_UART -DEARLY_UART_BASE=0xuart_address
to the CFLAGS.

72788291e6 memory: Map all RAM to the top, minus carveouts
This unbreaks dcp.py and other things that need to access reserved
regions. This way we don't have to start doing manual MMU maps, but
we're still safe from SErrors caused by hitting TZ carveouts.

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
