Subject: [PATCH v3 0/4] Add Xiaomi Poco F1 touchscreen support

In the first patch, I have updated the edt-ft5x06 touchscreen binding 
documentation. 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 for proper functioning 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.

In the second patch, I have enabled the qupv3_id_1 and gpi_dma1 as they
are required for configuring touchscreen. Also added the pinctrl
configurations. These are common for both the Poco F1 Tianma and EBBG
panel variant.

In the subsequent patches, I have enabled support for the Novatek NT36672a
touchscreen and FocalTech FT8719 touchscreen that are used in the Poco F1
Tianma and EBBG panel variant respectively.
