[PATCH v2 04/10] x86/Kconfig: drop X86_32_NON_STANDARD

["Mateusz Jończyk" <mat.jonczyk@o2.pl>]

This patch drops the "Support non-standard 32-bit SMP architectures"
configuration option. Currently, the only such an architecture is
STA2X11, so this option is useless. STA2X11 could now be selected
independently.

The dependency of X86_BIGSMP on X86_32_NON_STANDARD was dropped in
2009, in
commit 26f7ef14a76b ("x86: don't treat bigsmp as non-standard")
but the help text for X86_32_NON_STANDARD was not updated since.

CONFIG_X86_32_NON_STANDARD was used only in arch/x86/Kconfig, so it
could be dropped easily.

X86_32_NON_STANDARD depended on SMP, so
        (!SMP && !X86_32_NON_STANDARD) == !SMP
and
        (SMP || X86_32_NON_STANDARD) == SMP
