add verilator-only modifications to the HAL
...
verilator doesn't implement the TRNG, so the TRNG is bodged.
A warning is left in to help remind us/alert us if the bodge
is accidentally put into production.
the 'dabao' board type is introduced, which is the breakout board
codename.
camera and display are feature-gated behind their respective board
definitions.

slow down toggle rate on i2c so it is compatible with slow pullups

the strict verilog model has weak pull-ups which model the
"slowness" of the rise with an extended Z-condition that takes
3us to pull up to a solid 1.

mass storage is...somewhat stable now, on both linux and windows,
but there are some corrupt packets. need to look into whether
electrical issue, or if we're stomping the transfer buffers because
we've not managed them correctly.
Also need to reflect on how to turn this API into something
safer...the hardware is doing *so much* in this API, the driver
is basically global mutable state with arbitrary slices you can
write over the ends once you hand things off to the driver.

allocate large swathes of memory to camera

this is for higher resolution QR code scanning
makes it incompatible with simultaneous USB usage
however, when camera is off, the USB stack can be started, and
vice-versa. Basically, you can't both do active USB and camera
at the same time, but you can do one or the other.
