In order to make use of array info obtained from gpiod_get_array() and

Most users of get/set array functions iterate consecutive bits of data,
usually a single integer, while processing array of results obtained
from, or building an array of values to be passed to those functions.
Save time wasted on those iterations by changing the functions' API to
accept bitmaps.
Certain GPIO descriptor arrays returned by gpio_get_array() may contain
information on direct mapping of array members to pins of a single GPIO

The goal is to boost performance of get/set array functions while
processing GPIO arrays which represent pins of a signle chip in
hardware order. If resulting performance is close to PIO, GPIO API
can be used for data I/O without much loss of speed.
