Subject: [PATCH v2 2/2] Revert "arm64: dts: ti: am62-phyboard-lyra: Add overlay to increase cpu frequency to 1.4 GHz"

We now configure the a53_opp_table to include a 1.4 GHz node and set our
VDD_CORE to 0.85v in the k3-am62-phycore-som.dtsi. This change is to
match our PMIC which is now set to output 0.85v by default.

This reverts commit 7a5775a3da906dab059b8de60a2b88f6016cb4b8.
