ARM: dts: at91: sam9x60ek: classd: pull-down the L1 and L3 lines

Browse Source 
The L1 and L3 lines drive NMOS transistors that are OFF with a low level.
On the SAM9X60 EK board, if the pins corresponding to L1 and L3
have pull-ups enabled, there is an extra 2 x 30uA power consumption.
Use pull-downs for these 2 lines to remove the unnecessary power
consumption.

Fixes: 1e5f532c27 ("ARM: dts: at91: sam9x60: add device tree for soc and board")
