Subject: [PATCH] ARM: dts: rockchip: Add marvell BT irq config

Veyron Jaq and Mighty both use the Marvel 8897 WiFi+BT chip. Add wakeup
and pinctrl block to devicetree so the btmrvl driver can correctly
configure the wakeup interrupt.

The Veyron Mighty Chromebook (rk3288 based board) is missing the wake
configuration for Bluetooth. Without this change, the wake irq was not
configurable and wake on Bluetooth was broken.

I verified this change with additional changes in the Bluetooth driver
(the series is at https://patchwork.kernel.org/cover/11599101/). The
driver changes are not necessary for this dts change and shouldn't block
it.
