5726a8b968 ARM: at91/pm: rename function name: at91_slow_clock() --> at91_pm_suspend_sram_fn() 
As the file name is renamed, rename the function name at91_slow_clock()
--> at91_pm_suspend_sram_fn(), rename the function handler's name at the
same time.

828b98fa38 ARM: at91/pm: rename file name: pm_slowclock.S --> pm_suspend.S 
Because the sram function is used for both suspend to memory and the suspend
to standby mode, renaming is more elegant.
