Remove the divide by 4 operation to the under the hood SAI

[wendani]

This is to avoid the need and thus the confusion for application program to know
the mmu internal architecture

This change must have support from SAI change to reach the correct
config

- What I did
Delegate the divide-by-4 operation in setting the static threshold of egress queue for lossless traffic to the underneath SAI.

- How I did it
Change the buffers config json.

grep -rl 3995680 . | xargs sed -i 's/3995680/15982720/g'

grep -rl 10587408 . | xargs sed -i 's/10587408/42349632/g'   

grep -rl 11075584 . | xargs sed -i 's/11075584/44302336/g'

- How to verify it
Change the config_db.json on a7260 and dump the config after the change for verification.

Wenda,

You need to change 7260, 7060, and 6100 at the same time. Basically, any TH, TH2 platform with buffer configuration needs to be updated. And you also need to wait until the sai update is in place before merging it.

retest this please

Please let me merge it.

I need to get SAI upgraded first.

Thanks,
