ARM: dts: ifc6410: HACK add bt reset gpios to pwrseq

This patch adds BT gpios to reset sequence in SDCC4 pwrseq.
Ideally BT UART bus should get hold of pwrseq and do the reset, but for
now as a hack we let the BT reset done just with SDIO bus.

Things will change once the pwrseq is converted in to a proper platform
driver and other buses can use it.
