Subject: [PATCH] x86: intel-mid: make X86_INTEL_MID depending on SFI

Despite our intention to not make Intel MID dependent of SFI, it does
not reflect the current situation.
If SFI is not selected, Intel MID can't select APB_TIMER otherwise this
happens:

arch/x86/built-in.o: In function `apbt_set_mapping':
arch/x86/kernel/apb_timer.c:91: undefined reference to `sfi_get_mtmr'
arch/x86/kernel/apb_timer.c:109: undefined reference to `sfi_free_mtmr'
arch/x86/kernel/apb_timer.c:112: undefined reference to `sfi_get_mtmr'
arch/x86/kernel/apb_timer.c:91: undefined reference to `sfi_get_mtmr'
arch/x86/kernel/apb_timer.c:109: undefined reference to `sfi_free_mtmr'
arch/x86/kernel/apb_timer.c:112: undefined reference to `sfi_get_mtmr'

This patch solves such problem by adding SFI as dependence of
X86_INTEL_MID. As soon as we make Intel MID completely independent of
SFI this patch is safe to be reverted.

This patch is intended to be applied on kernel 3.13-rc release.

As a matter of curiosity, CONFIG_APB_TIMER does depend on CONFIG_SFI. But looks
like CONFIG_X86_INTEL_MID is able to bypass it.
Maybe we need to check Kconfig itself too?
