Most of the ISA_BUS_API drivers control GPIO via 8-bit ioport registers. Since updating any given GPIO line involves writing out all 8 bits for the respective register, it makes sense to add support for the GPIO set_multiple callback function so that multiple GPIO lines may be set more efficiently. This patchset adds such support in each respective driver.
