e1000e: fix force smbus during suspend flow
Commit 861e8086029e ("e1000e: move force SMBUS from enable ulp function
to avoid PHY loss issue") resolved a PHY access loss during suspend on
Meteor Lake consumer platforms, but it affected corporate systems
incorrectly.
A better fix, working for both consumer and corporate systems, was
proposed in commit bfd546a552e1 ("e1000e: move force SMBUS near the end
of enable_ulp function"). However, it introduced a regression on older
devices, such as [8086:15B8], [8086:15F9], [8086:15BE].
This patch aims to fix the secondary regression, by limiting the scope of
the changes to Meteor Lake platforms only.
