Convert the bindings for McASP controllers for TI SOCs from txt
to YAML schema.
Adds additional properties 'clocks', 'clock-names', 'power-domains',
'#sound-dai-cells' and 'port' which were missing from the txt file.
Removes properties 'sram-size-playback' and 'sram-size-capture'
since they are not used.
Adds 'dmas' and 'dma-names' in the example which were missing from
the txt file.
Changes 'interrupts' and 'interrupt-names' from optional to
required properties.
Changes 'op-modes', 'serial-dir' to optional properties as they are
not needed if the McASP is used only as GPIO.
Changes 'tdm-slots' to required property only for I2S operation mode.
Adds the yaml file in the 'MAINTAINERS' under the heading 'TEXAS
INSTRUMENTS ASoC DRIVERS'

Running 'make dtbs_check' with the schema in this patch gives the
following warnings. Consider if they are expected or the schema is
incorrect. These may not be new warnings.
Note that it is not yet a requirement to have 0 warnings for dtbs_check.
This will change in the future.

This is an error in the dts file. It has not been updated.

I re-ran the checks with the latest dt_schema. I didn't see these errors.
