[PATCH] net: tulip: winbond-840: remove never-true 486 CPU check

[Ethan Nelson-Moore <enelsonmoore@gmail.com>]

The winbond-840 driver contains a check for boot_cpu_data.x86 <= 4.
This field encodes the x86 generation (3 = 386, 4 = 486, etc).
Therefore, since 486 support was removed from the kernel in commit
8b793a92d862 ("x86/cpu: Remove M486/M486SX/ELAN support"), the
condition is always true. Remove the check.
