[PATCH v4 00/13 RESEND] AT91 pm cleanup for 3.20

[Wenyou Yang]

Hi Nicolas,

This version is rebased on the branch: at91-3.20-cleanup of the repository
	git://git.kernel.org/pub/scm/linux/kernel/git/nferre/linux-at91.git

It is purpose to clean up the PM code, includes the patches from Peter Rosin and Sylvain Rochet.

Since verifying the USB clock and USB PLL disabling before suspending to memory,
it aslo depends on the following patch serials from Sylvain:
	[PATCHv6 0/5] USB: gadget: atmel_usba_udc: Driver improvements
	[PATCHv7 0/6] USB: host: Atmel OHCI and EHCI drivers improvements

Removes CONFIG_AT91_SLOW_CLOCK config item to simply the PM config,
The suspend to standby mode uses the same sram function as the suspend to memory mode.
Remove some unused code.

Alexandr & Sylvain, Thank you very much for so many feedbacks.

Changes in v4:
 - Clear unused state argument in at91_pm_verify_clocks()
 - Remove pr_info("AT91:... slow_clock ? ..") in patch 07/13.

Changes in v3
 - Sylvain splits the patch in two
 - Add handling if no sram allocated for PM
 - Retain the STANDBY and SUSPEND_MEM select in at91_pm_enter.

Changes in v2:
 - Rebase on the at91-3.20-cleanup branch
 - Recover the verify clock condition, only for suspend to memory.
 - Collect ACK from Alexandre
 - Add the macro for PM mode
