71118af233 mraa.c: do not check return value of mraa_gpio_dir when used on muxes 
Doing so breaks galileo gen2 (gpio2) and others. Failing early is rather
pointless in any case so we may as well attempt the write, muxes do not
neccesarily have directions that work

3865bebe8d mmap: remove implementation of mmap gpio 
Instead of trying to have an implementation that covers most platforms
Leave all mmap up to platform definition. Through function pointers.

gpio_mmap_setup sets up the mmap

Within the internal gpio context struct two more function pointers now
exist mmap_read & mmap_write. They exist there so each context can its
own function for handling a write and read.
