Description
After #880, @aniktash reported the TFT on the MAX78000EVKIT was broken/blank. None of the demos were working.
It turns out that the driver simply did not initialize the vddioh member of an internal struct describing the SPI pins, so it was initialized to a random undefined value and optimized out by the compiler. The SPI pins then got initialized to 1.8V instead of 3.3V.
After this fix, all the TFT-based demos should be working again.
