isa: Decouple X86_32 dependency from the ISA Kconfig option
The introduction of the ISA_BUS option blocks the compilation of ISA drivers on non-x86 platforms. The ISA_BUS configuration option should not be necessary if the X86_32 dependency can be decoupled from the ISA configuration option. This patch both removes the ISA_BUS configuration option entirely and removes the X86_32 dependency from the ISA configuration option.
