x86: 32-bit EFI runtime service support: fixes in sync with 64-bit support

support according to fixes of x86_64 support.

- Delete efi_rt_lock because it is used during system early boot,
  before SMP is initialized.

- Change local_flush_tlb() to __flush_tlb_all() to flush global page
  mapping.

- Clean up includes.

- Revise Kconfig description.

- Enable noefi kernel parameter on i386.
