BRCM SDK 6.5.21 includes firmware updates (premier cancun) for TD3 platforms. The firmware update is required on TD3 platforms, which is packaged with BCMSAI 4.3.0.10.
**- How I did it**
Updated BCM config with a new variable that specifies the firmware package path. SDK uses this path to locate firmware packages and load during cold boot.

psu/sfp bug fixes to report correct states/status of hw
Corrected the ingress and egress lossy and lossless buffer pool and profile values.
Single pool for lossy and lossless traffic for PFC priority 3 and 4.
In HWSKU DellEMC-S5232f-P-100GG/25G/10G. Defaults to lossy profile. No Lossless support.
2 default mmu_init.data files (TD3-DEFAULT-LOSSLESS-P3P4 and "TD3-DEFAULT" created in SAI code. This will have cpu pool configuration and MMU init related configurations.
TD3-DEFAULT.data file is only supports lossy.
TD3-DEFAULT-LOSSLESS-P3P4.data file is supports lossless on P3 and P4.
