Removal of the <mach/id.h> include from ux500

Browse source 
- First an ACKed MFD patch deleting the only consumer
   of these cpu_is* functions outside of mach-ux500
 - Introduce a new local cpu_is_u8580() in this patch
   set to avoid clashing with other patch sets.
 - Finally de-globalize <mach/id.h>.

Merge tag 'ux500-no-idh' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson into next/cleanup

From Linus Walleij:
Removal of the <mach/id.h> include from ux500
- First an ACKed MFD patch deleting the only consumer
  of these cpu_is* functions outside of mach-ux500
- Introduce a new local cpu_is_u8580() in this patch
  set to avoid clashing with other patch sets.
- Finally de-globalize <mach/id.h>.

* tag 'ux500-no-idh' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson:
  ARM: ux500: de-globalize <mach/id.h>
  ARM: ux500: Introduce cpu_is_u8580()
  mfd: prcmu: delete pin control helpers
