6.6-stable review patch. If anyone has any objections, please let me know.

commit 903cc7096db22f889d48e2cee8840709ce04fdac upstream.
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.
