ARM: dts: msm: enable bta check mode for sharp wqxga panel

The display panel state can be checked by triggering a DSI bus turn
around (BTA) and waiting for BTA interrupt. If the interrupt times
out, a panel bad state is reported. Set EOT_TX_APPEND bit to avoid
overflow or ack errors for this panel.
