[ARM] pxa/spitz: Rework spitz
This huge patch mostly shuffles code. The spitz.c file contained terrible mess and needed a cleanup, here it is: 1) Made every part modular, components are not built in if not selected. 2) Removed loads of preprocessor goo, mostly "#ifdef MACH_AKITA .... #endif" and similar code. The kernel size will grow by a few kb now, but the file is much more readable. 3) Reworked SD/CF power setting function and made it reentrant. 4) Add ISL6271A regulator support 5) Correctly register WM8750 Signed-off-by: Marek Vasut <marek.vasut@gmail.com>
