For the SAMA5D4 SoC, some LCD lines are in conflict with useful peripherals.
Remove these lines and the lowest significant bit of a 24 bit LCD. It gives
us a RGB 777 configuration.

First fixes batch for AT91 on 4.0:
- PM slowclock fixes for DDR and timeouts
- fix some DT entries
- little defconfig updates
- the removal of a harmful watchdog option + its detailed documentation

Since turning on idle-halt in commit fe46aa67 (ARM: at91/dt: add
sam9 watchdog default options to SoCs), SoCs compatible with at91sam9260-wdt
no longer reboot if the watchdog times out while the CPU is in idle state.
Removing the 'idle-halt' flag that was set by default fixes this.

atmel,idle-halt property should be used with care, it actually makes the
watchdog not counting when the CPU is in idle state, therefore the
watchdog reset time depends on mean CPU usage and will not reset at all
of the CPU stop working while it is in idle state, which is probably not
what you want.
