Subject: [RFC PATCH] atmel_lcdfb Kconfig: remove long dependency line

Many Atmel SOC are embedding a LCD controller. This patch removes the long
dependency line for this Atmel LCD framebuffer driver configuration entry.
The ARCH_ATMEL_HAS_FB configuration option is located in the video Kconfig file
as it may be setup by ARM/AT91 and AVR32 chips.

Signed-off-by: Nicolas Ferre <nicolas.ferre@...el.com>

Beware, this proposition goes on top of at91sam9g45 & at91sam9g10 patchsets
already posted. My proposition is to wait for those series are queued before
applying this modification.
