Joule.md: Added Interrupt Pin assignment information

[swfFrg]

Verified that they worked with UBUNTU 16.04 LTS, Joule 570X, Tuchuck, BIOS #174, MRAA V1.5.1-24-g2ea6810

Setup:
use
"#define CHECK_ALL_80_PINS_CONFIGURATION_STATUS 1" if you want to check which pins are interrupt "configurable"
If not defined, one "specified pin" can be tested with the interrupt handler
3 pin switch connected: to 1.8v J13.12 and GND J12.39, switch center pin connected to "Pin55" J13.15 in example below

Qt pseudo code:
init mraa()
call initIsrPins()

void myISR {
static uint32_t myCnt = 0;
qDebug("Interrupt GPIO!!!! %d\n", myCnt++);
}

void initIsrPins(void)
{
mraa_result_t myStatus;
uint8_t myPinNum = 1;

#ifdef CHECK_ALL_80_PINS_CONFIGURATION_STATUS
for(myPinNum = 1; myPinNum <=80; myPinNum++)
{
mraa_gpio_context myIsr = mraa_gpio_init(myPinNum);
#else
mraa_gpio_context myIsr = mraa_gpio_init(55); // Manually enter Pin to test
#endif

   if(myIsr == 0)
       qDebug("FAILED mraa_gpio_context");
   else
   {
       myStatus = mraa_gpio_dir(myIsr, MRAA_GPIO_IN);
       if(myStatus != MRAA_SUCCESS)
           qDebug("FAILED mraa_gpio_dir");
       else
       {
           myStatus = mraa_gpio_isr(myIsr, MRAA_GPIO_EDGE_BOTH, (void (*)(void*)) myISR, NULL);
           if(myStatus != MRAA_SUCCESS)
               qDebug("FAILED mraa_gpio_isr");
           else
               qDebug("Passed:%d", myPinNum);
       }
   }

#ifdef CHECK_ALL_80_PINS_CONFIGURATION_STATUS
}
}

for(;;) { };
}

Please prefix your commit message with the file/module you are changing. E.g: "joule.md: Added Interrupt ...". Also, don't forget to sign-off your commit. You can use git commit --amend -s --no-edit, more info here.

Unfortunately changing the github issue title in the GUI is not enough, you need to actually amend to change the title, sign it off and push --force it.

If you get a change to fix this it would be great to merge it! Thanks
