gpio: i8255: Introduce the Intel 8255 interface library module
Exposes consumer library functions providing support for interfaces
compatible with the venerable Intel 8255 Programmable Peripheral
Interface (PPI).
The Intel 8255 PPI first appeared in the early 1970s, initially for the
Intel 8080 and later appearing in the original IBM-PC. The popularity of
the original Intel 8255 chip led to many subsequent variants and clones
of the interface in various chips and integrated circuits. Although
still popular, interfaces compatible with the Intel 8255 PPI are
nowdays typically found embedded in larger VLSI processing chips and
FPGA components rather than as discrete ICs.
A CONFIG_GPIO_I8255 Kconfig option is introduced by this patch. Modules
wanting access to these i8255 library functions should select this
Kconfig option, and import the I8255 symbol namespace.
