mb/google/kahlee: Select BT I2S PAD on ACP_BT_UART mux
bt-pad-enable property is used by kernel driver to set BT I2S PAD on ACP_BT_UART_PAD_SEL mux, for those platforms which use these pins for BT I2S. By default the pins are set for UART. BUG=b:72360151 TEST=Tested playback and capture on audio device connected to BT I2S Change-Id: Id76bfa1fa1dde904f02a03b0c15986ecb1bbcc97 Signed-off-by: Akshu Agrawal <akshu.agrawal@amd.com> Reviewed-on: https://review.coreboot.org/25653 Reviewed-by: Daniel Kurtz <djkurtz@google.com> Reviewed-by: Martin Roth <martinroth@google.com> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
