Subject: [PATCH] x86/Kconfig: simplify X86_UP_APIC handling

We don't really need a helper symbol for that. For one, it's
pointlessly getting set to Y for all configurations (even 64-bit ones).
And then the purpose can be fulfilled by suitably adjusting
X86_UP_APIC: Hide its prompt when PCI_MSI, and default it to PCI_MSI.
