It's not fully parameterised, as the IOMUX_SET macro requires the pin number
as part of the GPxx value.
This code compiles to the exact same instructions as blinkenTask,
so it's probably better to use the blinkenTask version.
There is no significant performance benefit to this way over the
blinkenTask version, so it's probably better to use the blinkenTask
version.
NOTE: This task isn't enabled by default, see the commented out line in user_init.
