Max Filippov 4949009eb8 xtensa: xtfpga: fix hardware lockup caused by LCD driver
LCD driver is always built for the XTFPGA platform, but its base address
is not configurable, and is wrong for ML605/KC705. Its initialization
locks up KC705 board hardware.

Make the whole driver optional, and its base address and bus width
configurable. Implement 4-bit bus access method.

Max Filippov c4ee0af3fa xtensa: remove NO_IRQ definitions
These definitions (-1) were correct when used as a hardware IRQ number,
but are incorrect as a mapped IRQ number.
