x86: Kill apic->cpu_to_logical_apicid()
After the previous patch, apic->cpu_to_logical_apicid() is no
longer used. Kill it.
For apic types with custom cpu_to_logical_apicid() which is also
used for other purposes, remove the function and modify its
users to do the mapping directly.
#ifdef's on CONFIG_SMP in es7000_32 and summit_32 are ignored
during conversion as they are not used for UP kernels.
