There are technically two i2c buses that are user accesible on minnowboard max
but the other one is on the high speed expansion header that I've never tested
and it's not mapped in mraa so leave this to 1 until someone enables it.

Fixes#251. default_i2c_bus was set to 7 before setting actual parameters for
it leading to obvious failure as 0 != 7

Not defining this causes undefined behaviour leading to the check mux_total
sometimes being true and asking the kernel to export all sorts of garbage gpio

Instead of plain char* to avoid need to malloc and do all the needed
error checking needed that goes along with that.

Used for getting the path to the character device under linux for uart
device. i.e. "/dev/ttyS0"
Adds paths to existing platforms.
Closes#84

Since gpios are +256 in 3.18+ kernels this stops dual definitions and possible
issues later on if errors are found

Whilst this value is not used because it's only required by the aio module it
is interesting to have this information if we want to expose it to the user

This should adjust the pinouts, at runtime, based on the current
kernel that's in use. The Linux kernel made a change between
3.17 and 3.18 ( specifically ea584595fc85e65796335033dfca25ed655cd0ed )
that changed the numbering for GPIOs. This obviously breaks everything
for mraa on the MinnowBoard MAX if you have a 3.18 or newer kernel.
