[PATCH 2/3] ARM: dts: imx6ull: add support for the esai interface

["Lothar Waßmann" <LW-bxm8fMRDkQLDiMYJYoSAnRvVK+yQ3ZXh@public.gmane.org>]

The address space taken by the UART8 on the i.MX6UL is used for the
ESAI interface on i.MX6ULL.

Since the ESAI unit on i.MX6ULL has two more bits in the TFCR register
(TFIN, TAENB) it deserves to get its own compatible string, though the
bits are currently not used by the driver.

Signed-off-by: Lothar Waßmann <LW-bxm8fMRDkQLDiMYJYoSAnRvVK+yQ3ZXh@public.gmane.org>
