Calling mraa_intel_edison_misc_spi() is not really needed, because the
GPIO 10..13 pins will be configured correctly when the user actually
inits them as GPIO pins. When using these pins for GPIO,
mraa_setup_mux_mapped() and mraa_intel_edison_gpio_init_post() will do
all this work based on the pin map and pinmodes for the Edison Arduino
board.
On the contrary, this function would break any user of the SPI bus
that is already running.

Edison SPI driver doesn't support LSB_FIRST mode, we will now return
_FEATURE_NOT_SUPPORTED instead of _INVALID_RESOURCE
for attempts to enable it.
Closes#22.

Gpio 111 controls the use of hardware CS by the edison kernel's SPI driver.
This is an issue as that CS will go high between every byte transmitted. The
solution is to let gpio 111 alone and let the driver decide what is best. This

This reworks the mraa_intel_edison_i2c_freq() function. i2c_dw_sysnode is a
folder not a file so we need to grab the mode file from that folder. We now
also support i2c-1 frequency changing

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.

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