asm-generic: add legacy I/O header files
The dma.h, hw_irq.h, serial.h and timex.h files originally
described PC-style i8237, i8259A, i8250, i8253 and i8255 chips
as well as the VGA style text mode graphics.
Modern architectures live happily without these specific
interfaces, but a few definitions from these headers keep
getting used in common code.
The new generic headers are what most architectures use
anyway nowadays, just implementing the minimal definitions.
