arm64: dts: ti: k3-am62-phycore-som: Add 128MiB of global CMA
Reserve 128MiB of global CMA which is also marked as re-usable
so that OS can also use the same if peripheral drivers are not using
the same.
Based on the use case described in commit c43dd2fe5316 ("arm64: dts: ti:
k3-am62x-sk-common: Reserve 128MiB of global CMA").
