[PATCH 3/3] Documentation/arch/x86: remove obsolete vdso32=2 compatibility note

[Thorsten Blum <thorsten.blum@linux.dev>]

Commit b0b49f2673f0 ("x86, vdso: Remove compat vdso support") removed
compat vDSO support and documented vdso32=2 as an alias for vdso32=0.

However, since commit c06989da39cd ("x86/vdso: Ensure vdso32_enabled
gets set to valid values only"), vdso32_setup() accepts only 0 and 1.

Remove the obsolete vdso32=2 compatibility note and document only the
supported values.
