The EFI HTTP boot puts the ISO installer image at some location in
memory. Information about this image has to be passed on to the OS
kernel, which is done by adding a persistent memory(pmem) node to the
devicetree(DT) that is passed to the OS. The OS kernel then gets
information about the presence of this ISO image and proceeds with the
installation.
In U-Boot, this ISO image gets mounted as a memory mapped blkmap
device slice, with the 'preserve' attribute. Add a helper function
which iterates through all such slices, and invokes a callback. The
callback adds the pmem node to the DT and removes the corresponding
memory region from the EFI memory map. Invoke this helper function as
part of the DT fixup which happens before booting the OS.

Some blkmap memory mapped devices might have to be relevant even
after U-Boot passes control to the next image as part of the platform
boot. An example of such a mapping would be an OS installer ISO image,
information for which has to be provided to the OS kernel. Use the
'preserve' attribute for such mappings. The code for adding a pmem
node to the device-tree then checks if this attribute is set, and adds
a node only for mappings which have this attribute.

One of the problems an OS may face, when running in EFI, is that
a mounted ISO, after calling ExitBootServices goes away, if that ISO
is resident in RAM memory as a ramdisk.
ACPI has NFIT and NVDIMM support to provide ramdisks to the OS, but we
don't have anything in place for DTs. Linux and device trees have support
for persistent memory devices. So add a function that can inject a pmem
node in a DT, so we can pass information on the ramdisk the OS.

Since we already know the address change the prototype to return an int.

This structure is supposed to handle any type of booting
programmatically, i.e. without needing a command to be executed. Move
the x86-specific members into it and use it instead of
struct zboot_state. Provide a macro so access is possible without adding
lots of #ifdefs to the code.
This will allow the struct to be used for all four types of booting
(bootm, bootz, booti and zboot).
Call bootm_init() to init the state, to match other boot methods.
Note that some rationalisation could be performed on this. But this
is tricky since addresses are stored as strings in several places. Also
some strings combine multiple arguments into one. So to keep this task
somewhat manageable, we content ourselves with just getting everything
into the same struct

Upcoming patches are switching the memory mappings to RW, RO, RX
after the U-Boot binary and its data are relocated. Add
annotations in the linker scripts to and mark text, data, rodata
sections and align them to a page boundary.
It's worth noting that .efi_runtime memory permissions are left
untouched for now. There's two problems with EFI currently.
The first problem is that we bundle data, rodata and text in a single
.efi_runtime section which also must be close to .text for now.
As a result we also dont change the permissions for anything contained
in CPUDIR/start.o. In order to fix that we have to decoule .text_rest,
.text and .efi_runtime and have the runtime services on their own
section with proper memory permission annotations (efi_rodata etc).
The efi runtime regions (.efi_runtime_rel) can be relocated by the OS when
the latter is calling SetVirtualAddressMap. Which means we have to
configure those pages as RX for U-Boot but convert them to RWX just before
ExitBootServices. It also needs extra code in efi_tuntime relocation
code since R_AARCH64_NONE are emitted as well if we page align the
section.
Due to the above ignore EFI for now and fix it later once we have the
rest in place.
