[GIT PULL] at91: cleanup for 4.1 #1

[Nicolas Ferre]

Arnd, Olof, Kevin,

Big PM cleanup by Wenyou this time. I'll add other cleanup material by
Alexandre on top of it real soon.
Note that these patches are stacked on top of all the "fixes" tags that you
already took (at91-fixes3): it was needed for avoiding conflicts in the PM code.

Thanks, best regards,

The following changes since commit 5e7f82d73057a4b99643999e02c036cfbf1ed3ba:

  ARM: at91/pm: flush data cache and clean, invalidate and disable the L2 cache (2015-03-13 13:34:55 +0100)

----------------------------------------------------------------
First batch of cleanup for 4.1:
- little phy fixup that is not needed anymore
- hudge cleanup of the PM code:
  - removal of "use slow clock" option => always use this for suspend to RAM
  - quicker suspend as the asm function is copied only once to SRAM
  - use of the same asm function for "standby" and "mem" types of suspend
    actions
  - adaptation to the ARMv7 processors
