Subject: [PATCH 1/2] dt-bindings: coresight: qcom,coresight-tpda: Fix too many 'reg'

Binding listed variable number of IO addresses without defining them,
however example DTS code, all in-tree DTS and Linux kernel driver
mention only one address space, so drop the second to make binding
precise and correctly describe the hardware.

Fixes: a8fbe1442c2b ("dt-bindings: arm: Adds CoreSight TPDA hardware definitions")
