Subject: [PATCH v2 00/12] AT91 pm cleanup for 3.20

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 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
