mb/google/poppy/variants/atlas: move WiFi wake to GPP_B7

The latest rev. of the atlas board moves the WiFi wake source from
WAKE# to GPP_B7.  The original GPP_A0 in the device tree is just
wrong.  This also reconfigures DW1 to the GPP_B group so we can use
GPP_B7 as a wake source.

GPP_B7 is still configured as a no-connect in gpio.c, so this doesn't
actually enable WiFi wake.  We'll follow up with another patch to set
up GPP_B7 properly on boards that support it.
