x86/platform: Only allow CONFIG_EISA for 32-bit

Browse source

[ Upstream commit 976ba8da2f ]

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.
