[PATCH v7 057/120] dmaengine: ioatdma: Remove custom UP local APID IC code

Since

  commit b4033c1715cb ("[PATCH] PCI: Change MSI to use physical delivery mode always")

and a cpu_physical_id() implementation exists for UP kernels.

Replace the driver's private UP APIC ID implementation with the kernel's
generic cpu_physical_id() helper.  This also avoids a direct CPUID query.
