[PATCH net v2] net: ti: icssg-prueth: Fix start counter for ft1 filter

[MD Danish Anwar]

The start counter for FT1 filter is wrongly set to 0 in the driver.
FT1 is used for source address violation (SAV) check and source address
starts at Byte 6 not Byte 0. Fix this by changing start counter to
ETH_ALEN in icssg_ft1_set_mac_addr().

Changes from v1 to v2:
*) Using ETH_ALEN instead of hardcoding the values to 6 as suggested by
   Florian Fainelli <f.fainelli@gmail.com>

v1: https://lore.kernel.org/all/20240524093719.68353-1-danishanwar@ti.com/
