srideepDell 60a7f4d653 [device]: Add a new supported device DellEMC s5248f (#3547)
* Switch Vendor: DellEMC
* Switch SKU: s5248F
* ASIC Vendor: Broadcom
* Swich ASIC: Trident3
* Port Configuration: 48x25G,4x100G,2x200G
* SONiC Image: sonic-broadcom.bin

* Changes Include ipmitool implementation for platform_sensors script is inclued in pmon startup
* Added 25G,10G configruation(25G is default) 1-48FP. 4x100G,2x200G (49-54 FP)
* LED support for s5248f
