Subject: [PATCH 15/26] x86 STA2X11: remove the sta2x11-mfd driver.
This patch removes the mfd driver for the Connext chip, the final goal
being to create platform devices through the new OF enabled version of
the pci to amba bridge.
Most of the sta2x11-mfd.h header file is moved to asm/sta2x11.h.
Platform drivers for sctl, scr, apbreg and apb_soc_regs are moved under
arch/x86/platform/sta2x11.c (but the common probe function is empty at
the moment, since we have no struct sta2x11_mfd anymore).
Makefiles and Kconfigs are updated accordingly (note that REGMAP_MMIO is
now selected by CONFIG_STA2X11, not CONFIG_STA2X11_MFD, which does not
exist anymore).
