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.
