GPIO: Add driver for 74xx-ICs with MMIO access
This patch adds driver to support GPIO functionality for 74xx-compatible
ICs with MMIO access. Compatible models include:
1 bit: 741G125 (Input), 741G74 (Output)
2 bits: 742G125 (Input), 7474 (Output)
4 bits: 74125 (Input), 74175 (Output)
6 bits: 74365 (Input), 74174 (Output)
8 bits: 74244 (Input), 74273 (Output)
16 bits: 741624 (Input), 7416374 (Output)
