net: dsa: bcm_sf2: Only 7278 supports 2Gb/sec IMP port
[ Upstream commit de34d7084edd069dac5aa010cfe32bd8c4619fa6 ]
The 7445 switch clocking profiles do not allow us to run the IMP port at
2Gb/sec in a way that it is reliable and consistent. Make sure that the
setting is only applied to the 7278 family.
