This commit adds new code to support z9100 PFC T0 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. The T0 configs supports
fan-out of 100G ports on Z9100. Added new config.bcm for fanout of 100G
ports and tested the fanout by sending traffic using bcmcmd, new config.bcm
file will be copied to /usr/share/sonic/hwsku/th-z9100-8x100-48x50G.config.bcm.
The sai.profile file is updated to point to hwsku directory.
