Remove unused code. The padconf code has been replaced with the
generic pinctrl(4) driver and intc(4) now attaches using the device
tree.

If you use sys/param.h, you don't need sys/types.h

Remove unused table driven omgpio bits.

Remove now unused definitions for drivers that have been converted to
use the fdt.

After factorizing armv7_machdep code here is an effort to factorize all
the code present in omap/omap.c imx/imx.c and sunxi/sunxi.c

All this code looks quite the same, so we move it in a generic armv7/armv7.c

This is a step closer to only one kernel for all armv7 boards.

In the future, we shouldn't have one port port ARM SoC, that's just
ridiculous. This is the first step for a common and generic ARM port
for ARMv7 SoCs.
