[device/dell] Add z9100 pfc T0 support
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. Signed-off-by: Harish Venkatraman <[email protected]>
