[ Upstream commit 976ba8da2f3c2f1e997f4f620da83ae65c0e3728 ]
The CONFIG_EISA menu was cleaned up in 2018, but this inadvertently brought the option back on 64-bit machines: ISA remains guarded by a CONFIG_X86_32 check, but EISA no longer depends on ISA.
The last Intel machines ith EISA support used a 82375EB PCI/EISA bridge from 1993 that could be paired with the 440FX chipset on early Pentium-II CPUs, long before the first x86-64 products.
