Subject: [PATCH v2 0/4] Add Xiaomi Poco F1 touchscreen support

In the first patch, I have added the "panel" property to 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. Add the panel property which optionally allows to link panel
to the touchscreen.

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.
