Adding a new 'snps,filter-se0-fsls-eop quirk' DT quirk to dwc3 core to set GUCTL1 BIT 29. When set, controller will ignore single SE0 glitch on the linestate during transmission. Only two or more SE0 is considered as valid EOP on FS/LS port. This bit is applicable only in FS in device mode and FS/LS mode of operation in host mode.
