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.

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.

The gpio_close_pre was put on the wrong board definition. So calling close of
GPIO pin on mini-board caused a fault

Made like changes to Edison to cache the output enable.
Note: different than Edison as the pin structure holds enable pin number
instead of external array.
2nd note: noticed PU resistors are also in structure but there is also
external array.
