[device/dell] Add z9100 pfc T1 support (#1707)
Browse files Browse the repository at this point in the history 
This commit adds new code to support z9100 PFC T1 support with
broadcom recommended MMU settings for PFC feature.

Unit tested the setting by loading sonic-broadcom.bin and checking
the hardware for the values from the JSON file. Added the config.bcm
file th-z9100-32x100G.config.bcm to this folder and updated the
sai.profile file to point to hwsku directory. sai.profile now
points to /usr/share/sonic/hwsku/th-z9100-32x100G.config.bcm
