ARM: mmp: remove device definitions

Since all board support is now gone, a lot of code in the
platform is no longer called and can be removed as well.
The remaining parts are:

 * The interrupt numbers for pxa910 are still needed for the
   power management support.

 * The 'mfp' device is still statically initialized from
   platform code, though this could be moved into the
   pinctrl code

 * The CPU identification code is used for the cpu_is_mmp*()
   macros.

- * NOTE: the MFPR register bit definitions on PXA168 processor lines are a
- * bit different from those on PXA3xx.  Bit [7:10] are now reserved, which
- * were SLEEP_OE_N, SLEEP_DATA, SLEEP_SEL and the LSB of DRIVE bits.
- *
- * To cope with this difference and re-use the pxa3xx mfp code as much as
- * possible, we make the following compromise:
- *
- * 1. SLEEP_OE_N will always be programmed to '1' (by MFP_LPM_FLOAT)
- * 2. DRIVE strength definitions redefined to include the reserved bit
- *    - the reserved bit differs between pxa168 and pxa910, and the
- *      MFP_DRIVE_* macros are individually defined in mfp-pxa{168,910}.h
- * 3. Override MFP_CFG() and MFP_CFG_DRV()
- * 4. Drop the use of MFP_CFG_LPM() and MFP_CFG_X()
