Specify the properties which are essential and which are not for the
Tegra I2C driver to function correctly. This was not added correctly when
the TXT binding was converted to yaml. All the existing DT nodes have
these properties already and hence this does not break the ABI.
dmas and dma-names which were specified as a must in the TXT binding
is now made optional since the driver can work in PIO mode if dmas are
missing.

Properties are expected to be defined in top-level "properties:" block
and further customized in "if:then:". Only one variant has power
domains, so add respective top-level property and disallow it for other
devices.

Both xxx and xxx-names properties with variable number of items should
be constrained in each "if:then:". Add missing constraints for clocks,
since we have such for clock-names.

"if:then:" block for Tegra114 and Tegra120 I2C controllers has the same
"then" part (same clocks), so combine them.

The reference i2c-controller.yaml already defines 'address-cells' and
'size-cells', so drop them from list of properties.
