dt-bindings: display: ti,am65x-dss: Add support for common1 region

Browse Source 
TI keystone display subsystem present in AM65, AM62 and AM62A SoC support
two separate register spaces namely "common" and "common1" which can be
used by two separate hosts to program the display controller as described
in respective Technical Reference Manuals [1].

The common1 register space has similar set of configuration registers as
supported in common register space except the global configuration
registers which are exclusive to common region.

This adds binding for "common1" register region too as supported by the
hardware.
