[PATCH] ARM: dts: imx6ull: Use the correct name for ESAI_TX0

[Fabio Estevam]

According to the i.MX6ULL Reference Manual, pad CSI_DATA07 may
have the ESAI_TX0 functionality, not ESAI_T0.

Also, NXP's i.MX Config Tools 10.0 generates dtsi with the
MX6ULL_PAD_CSI_DATA07__ESAI_TX0 naming.

Add an entry for the correct name and still keep the old one to
avoid potential breakage.
