ARM: at91/pm: remove CONFIG_AT91_SLOW_CLOCK config option
The slow clock always exists, selecting CONFIG_AT91_SLOW_CLOCK config is unnecessary for the suspend to memory mode. For this mode the master clock should always switch to the slow clock.

comment "AT91 Feature Selections"
-config AT91_SLOW_CLOCK
- bool "Suspend-to-RAM disables main oscillator"
- depends on SUSPEND
- help
- Select this if you want Suspend-to-RAM to save the most power
- possible (without powering off the CPU) by disabling the PLLs
- and main oscillator so that only the 32 KiHz clock is available.
-
- When only that slow-clock is available, some peripherals lose
- functionality. Many can't issue wakeup events unless faster
- clocks are available. Some lose their operating state and
- need to be completely re-initialized.
