Add pin commands. Old mraa_setup_mux_mapped style is used for other boards
(pincmd = PINCMD_UNDEFINED) where pincmds are not defined.Remove useless
pullup_enable code, Galileo Gen2: review all pin mux and add commands Galileo
Gen2: remove doubled functionality: mraa_intel_galileo_gen2_i2c_init_pre and
mraa_intel_galileo_gen2_uart_init_pre. Galileo Gen2: fix "Invalid AIO pin
specified - do you have an ADC?" error. Galileo Gen2: pullup/pulldown
resistors are disabled during UART/GPIO/SPI/I2C/UIO initialization. Use
mraa_gpio_mode to enable resistors.

Switch to using calloc on all calls to malloc where the memory isn't
initialized. For things like the mraa_board_t, not allocating all to zero
causes issues such as with the sub_platform member, where if that's not zero
mraa_get_platform_type will try to dereference a random memory location for the
sub_platform->platform_name, which can result in segmentation faults and other
issues.
Note that in some places where immediately after the malloc call is a copy
operation, there is no need for calloc, as all the memory gets overwritten
anyways, but in cases where there may or may not be memory written to (such as
in mraa_file_contains, with reading from a file), even though in most cases the
memory is overwritten, it could be the case that the read operation does
nothing, but the memory still has non-zero values, by virtue of the fact it
wasn't overwritten.

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

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.
