Subject: [PATCH v2 0/3] arm64: dts: qcom: Add EL2 overlay support

We have recently added initial EL2 overlay support for Lemans and there
it was not disabling zap-shader as GPU changes were not available. Lets
disables the zap-shader there. And in the similar lines add support for
Monaco and Talos SoC variants as well which support EL2 configuration.

Talos GPU changes are not merged so its overlay file has dependency
on https://lore.kernel.org/lkml/20260121-qcs615-spin-2-v7-0-52419b263e92@oss.qualcomm.com/#t

Changes in v2:
 - Added patch to disable zap-shader for Lemans -El2 configuration.
 - Address comments on V1 about comments placement and sorting the
   labels.
 - Added dependency.
 - Link to v1: https://lore.kernel.org/lkml/20260123103503.1259645-1-mukesh.ojha@oss.qualcomm.com/
