The Elan eKTH8D18 touchscreen controller is an I2C HID device with a longer boot-up time. Power sequence timing wise it is compatible with the eKTH6A12NAY, with a power-on delay of at least 5ms, 20ms out-of-reset for I2C ack response, and 150ms out-of-reset for I2C HID enumeration, both shorter than what the eKTH6A12NAY requires. Enumeration and subsequent operation follows the I2C HID standard. Add a compatible string for it with the ekth6a12nay one as a fallback. No enum was used as it is rare to actually add new entries. These chips are commonly completely backward compatible, and unless the power sequencing delays change, there is no real effort being made to keep track of new parts, which come out constantly. Also drop the constraints on the I2C address since it's not really part of the binding.

In Xiaomi Poco F1 (qcom/sdm845-xiaomi-beryllium-ebbg.dts), the FocalTech FT8719 touchscreen is integrally connected to the display panel (EBBG FT8719) and thus should be power sequenced together with display panel using the panel property. Since the edt-ft5x06 touchscreen binding uses almost all the properties present in touchscreen.yaml, let's remove additionalProperties: false and use unevaluatedProperties to include all the properties, including the needed panel property.
