iio: stx104: Implement get_multiple callback
The Apex Embedded Systems STX104 series of devices provides 4 TTL compatible lines of inputs accessed via a single 4-bit port. Since four input lines are acquired on a single port input read, the STX104 GPIO driver may improve multiple input reads by utilizing a get_multiple callback. This patch implements the stx104_gpio_get_multiple function which serves as the respective get_multiple callback.
