eliminate R209 and tie Iota VLMEM directly to UPR
We already eliminated R210 (VLMEM pull-down option) earlier, because
our simplified LCD power supply and reset line wiring is incompatible
with 1.8V MEMIF. But with VLMEM always needing to be high, a pull-up
resistor offers no advantage over a direct tie to UPR, so let's
eliminate the superfluous resistor.
