lib: add support for stmp-style devices
MX23/28 use IP cores which follow a register layout I have first seen on STMP3xxx SoCs. In this layout, every register actually has four u32: 1.) to store a value directly 2.) a SET register where every 1-bit sets the corresponding bit, others are unaffected 3.) same with a CLR register 4.) same with a TOG (toggle) register Also, the 2 MSBs in register 0 are always the same and can be used to reset the IP core. All this is strictly speaking not mach-specific (but IP core specific) and, thus, doesn't need to be in mach-mxs/include. At least mx6 also uses IP cores following this stmp-style. So: Introduce a stmp-style device, put the code and defines for that in a public place (lib/), and let drivers for stmp-style devices select that code. To avoid regressions and ease reviewing, the actual code is simply copied from mach-mxs. It definately wants updates, but those need a seperate patch series. Voila, mach dependency gone, reusable code introduced. Note that I didn't remove the duplicated code from mach-mxs yet, first the drivers have to be converted.
