Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and
drop the unnecessary inclusion of asm/global_data.h.

Headers should be included directly by the files that need them,
rather than indirectly via global_data.h.

This returns a devicetree and updates a parameter with an error code.
Swap it, since this fits better with the way U-Boot normally works. It
also (more easily) allows leaving the existing pointer unchanged.

No yaks were harmed in this change, but there is a very small code-size
reduction.

For sifive, the OF_BOARD option must be set for the function to be
called, so there is no point in checking it again. Also OF_SEPARATE is
defined always.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

The migration deadline for moving to DM_SCSI was v2023.04. A further
reminder was sent out in August 2023 to the remaining platforms that had
not migrated already, and that a few more over the line (or configs
deleted).

With this commit we:
- Rename CONFIG_DM_SCSI to CONFIG_SCSI.
- Remove all of the non-DM SCSI code. This includes removing other
  legacy symbols and code and removes some legacy non-DM AHCI code.
- Some platforms that had previously been DM_SCSI=y && SCSI=n are now
  fully migrated to DM_SCSI as a few corner cases in the code assumed
  DM_SCSI=y meant SCSI=y.

The DT used for Calxeda Highbank and Midway systems exposes a "system
registers" block, modeled as a DT subnode.
This includes several clocks, including the two fixed clocks for the
main oscillator and timer.

So far U-Boot was ignorant of this special construct (a "clocks" node
within the "hb-sregs" node), as it didn't need the PLL clocks in there.
But that also meant we lost the fixed clocks, which form the base for
the UART baudrate generator and also the SP804 timer.

To allow the generic PL011 and SP804 driver to read the clock rate,
add a simple bus driver, which triggers the DT node discovery inside this
special node. As we only care about the fixed clocks (we don't have
drivers for the PLLs anyway), just ignore the address translation (for
now).

The binding is described in bindings/arm/calxeda/hb-sregs.yaml, the DT
snippet in question looks like:

=======================
	sregs@fff3c000 {
		compatible = "calxeda,hb-sregs";
		reg = <0xfff3c000 0x1000>;

		clocks {
			#address-cells = <1>;
			#size-cells = <0>;

			osc: oscillator {
				#clock-cells = <0>;
				compatible = "fixed-clock";
				clock-frequency = <33333000>;
			};
			....
		};
	};
=======================

OF_HOSTFILE is used on sandbox configs only.  Although it's pretty
unique and not causing any confusions,  we are better of having simpler
config options for the DTB.

So let's replace that with the existing OF_BOARD.  U-Boot would then
have only three config options for the DTB origin.
- OF_SEPARATE, build separately from U-Boot
- OF_BOARD, board specific way of providing the DTB
- OF_EMBED embedded in the u-boot binary(should not be used in production

Rob does not have access to any Calxeda systems anymore, also has
expressed a lack of interest in those systems in the past.

I have multiple working Midway nodes under my desk in the office, so
am happy to take over maintainership.

So far U-Boot was hard coding a (surely sufficient) memory size of 512
MB, even though all machines out there have at least 4GB of DRAM.
Since U-Boot uses its memory knowledge to populate the EFI memory map,
we are missing out here, at best losing everything beyond 4GB on Midway
boxes (which typically come with 8GB of DRAM).

Since the management processor populated the DT memory node already with
the detected DRAM size and configuration, we use that to populate
U-Boot's memory bank information, which is the base for the UEFI memory
map.
This finally allows us to get rid of the NR_DRAM_BANKS=0 hack, that we
had in place to avoid U-Boot messing up the DT memory node before
loading the kernel.

Also, to cover the whole of memory, we need to enable PHYS_64BIT.
