dt-bindings: arm: qcom: Document additional skus for sc7180 pazquel360

pazquel360 is an extension project based on pazquel.
We create 3 sku on pazquel360:
   sku 20 for LTE with physical SIM _and_ eSIM and WiFi
   sku 21 for WiFi only
   sku 22 for LTE with only a physical SIM
 Both sku20 and sku22 are LTE SKUs.
 One has the eSIM stuffed and one doesn't.
 There is a single shared device tree for the two.
