Subject: [PATCH v2 2/2] Revert "dt-bindings: cache: qcom,llcc: correct QDU1000 reg entries"

This reverts commit f0f99f371822c48847e02e56d6e7de507e18f186.

QDU1000 has 7 register regions. The earlier commit 8e2506d01231
("dt-bindings: cache: qcom,llcc: Add LLCC compatible for QDU1000/QRU1000")
to add llcc compatible was reflecting the same, but dtsi change for
QDU1000 was not aligning with its binding. Later, commit f0f99f371822
("dt-bindings: cache: qcom,llcc: correct QDU1000 reg entries") was merged
intended to fix this misalignment.

After the LLCC driver refactor, each LLCC bank/channel need to be
represented as one register space to avoid mapping to the region where
access is not there. Hence, revert the commit f0f99f371822 ("dt-bindings:
cache: qcom,llcc: correct QDU1000 reg entries") to align QDU1000 llcc
binding with its dtsi node.
