Apply the revised Cham6 pool allocation to physical and simulation SKUs.

Why I did it

The Cham6 buffer pool sizes needed to be aligned with the latest buffer-sizing Excel calculations.

How I did it

Updated the ingress lossless, ingress lossy, egress lossless, and egress lossy pool sizes for the affected Cham6 physical and simx SKUs. Applied the calculated values consistently to both T0 and T1 buffer templates.

How to verify it

Recalculate the affected Cham6 SKUs using the latest buffer-sizing Excel workbook.
Confirm that the generated pool sizes match the updated Jinja2 templates.
Verify that corresponding physical and simx SKUs use consistent values.
Generate the buffer configuration for the affected T0 and T1 SKUs and confirm that it renders successfully.
