[PATCH net-next v2 2/3] net: gianfar_ptp: Rename FS bit to FIPERST

[Florian Fainelli <f.fainelli@gmail.com>]

FS is a global symbol used by the x86 32-bit architecture, fixes builds
re-definitions:

>> drivers/net/ethernet/freescale/gianfar_ptp.c:75:0: warning: "FS"
>> redefined
    #define FS                    (1<<28) /* FIPER start indication */
