kexec: add BSS to resource tree
Add the BSS to the resource tree just as kernel text and kernel data are in the resource tree. The main reason behind this is to avoid crashkernel reservation in that area. While it's not strictly necessary to have the BSS in the resource tree (the actual collision detection is done in the reserve_bootmem() function before), the usage of the BSS resource should be presented to the user in /proc/iomem just as Kernel data and Kernel code. Note: The patch currently is only implemented for x86 and ia64 (because efi_initialize_iomem_resources() has the same signature on i386 and ia64).
