loader changes for vexii

primarily modify the loading method to mark pages with A/D flags
as needed to work around lack of A/D handling in the trap handler
of Xous.
Also inside main.rs is a todo list for polishing off the vex-ii
port and turning into something actually sustainable for Denarius
once we have more of a full SoC model available.

KB_C2 pin just died?
...
KB_C2 pin on this test board just got shorted to ground internally
in the chip. I think it may have been due to power glitches
when the ammeter was switching modes feeding through and causing
trouble for the system.
Anyawys, disable that row and remap some keys so we can continue
with testing. MPW boards will hopefully be retired soon enough...

try to eliminate floating point debug prints

for some reason the loader has a lot of code devoted to formatting
debug prints of floating point numbers. In the version of the loader
that's being built for production I think we shouldn't need any
of this?
