CorebootModulePkg/CbSupportDxe: Remove duplicated IO Space addition

Since UefiCpuPkg's CpuDxe Driver already adds Local Apic's MMIO space to
GCD, CorebootModulePkg's CbSupportDxe should not do this again. Doing this
again causes error return status from GCD service, and ASSERT (FALSE) with
debug build, so the duplicated addition is removed.
