Add support for the Novatek NT36672A touchscreen variant found on the Xiaomi Redmi Note 6 Pro (tulip) which uses a different wake_type value (0x02 instead of 0x01). The touchscreen was failing to initialize with error -5 due to the wake_type parameter mismatch during probe. This adds a new chip data structure for the e7t variant with the correct wake_type value.
