dt-bindings: arm: qcom: Document Microsoft Surface Pro 11

Add the compatibles for the Qualcomm-based Microsoft Surface Pro 11,
using its Denali codename.

The LCD models are using the Qualcomm Snapdragon X1 Plus (X1P64100),
the OLED ones are using the Qualcomm Snapdragon X1 Elite (X1E80100).

Due to the difference in how the built-in panel is being handled
between the OLED variant and LCD one, it is required to have two
separate DTBs, so document the compatible string for both variants.
