It does?  Why?  One of the functions of the vendor specific Kconfig
options is to improve UX when configuring the kernel, if you're building
for a particular SoC or set of SoCs then we can avoid showing you
drivers that can never possibly appear in your system which makes life
a bit easier.  We shouldn't be using them in the code itself but they do
help people in Kconfig.
