net: atmel_macb Kconfig: remove long dependency line

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