Bulk set gpio direction support

[drakejest]

Hello would it be possible to add a function for bulk setting of INPUT/OUTPUT of the GPIO? im currently using 5 of these and 80 lines of code is used up for just setting the direction of the GPIO, i mean its not really a bad thing, just to make the code cleaner to look at. Alternatively having a function to read/write register directly would also be good as i can do the bulk setting of gpio direction there.

Thanks ! :)
