ARM: mach-stmp37xx: remove mach
This mach has not seen any updates since the initial inclusion besides generic cleanup. Furthermore: - It has a lot of reinvented interfaces, leaking all sorts of mach-related includes into the drivers. One example is the dmaengine which does not use the linux dmaengine-API but some privately exported symbols. So, drivers cannot be reused. mach-mxs is very similar and does it better. - It can be doubted that this worked at all. Check the DMA routines in stmp37xx.c for copy/paste bugs. A lot of APBX-related stuff is actually writing into registers for APBH. - There is only one board defined (which I couldn't find any trace of despite being a development board). In this board, only two devices have resources, the debug uart and the application uart. Neither of those have the needed custom drivers merged (and never will). debug uart is amba-pl011 which has an in-kernel driver without the mach-specific-stuff. appuart has a driver which was introduced for mach-mxs, and this one is reusable for a properly done mach. So, this single board registers only unsupported devices and the generic code looks suspicious and has poor design. Delete this stuff. If there is interest, it is wiser to restart using mach-mxs.
