dm: core: add kernel dtb version 2 mechanism support

The V2 mechanism:
- both of U-Boot and kernel's *ALL* devices are exist in dm tree.
- put the necessary U-Boot devices in the head of device uclass list.
- the both existence policy don't require phandle fixup any more.
- it is for the next generation(rk3588 ...) or necessary platforms.
- traverse u-boot fdt phandle if not found in kernel fdt, because
the U-Boot framework gets phandle by of_root(from fdt) but not dm_root(from dm).
The V1 mechanism(legacy):
- U-Boot: only some necessary U-Boot devices(storage, crypto...) in dm tree.
- kernel: all the devices(except the U-Boot only) in dm tree.

The commit (bd3ad955a3 scripts/dtc: phandle index start from 0x1000000) is
necessary for this v2 mechanism.

UPSTREAM: dm: blk: Use uclass_find_first/next_device() in blk_first/next_device()

This patch changes the calls to uclass_first/next_device() in blk_first/
next_device() to use uclass_find_first/next_device() instead. These functions
don't prepare the devices, which is correct in this case.

With this patch applied, the "usb storage" command now works again as
expected:

=> usb storage
Device 0: Vendor: SanDisk Rev: 1.00 Prod: Ultra
Type: Removable Hard Disk
Capacity: 58656.0 MB = 57.2 GB (120127488 x 512)

Without this patch, it used to generate this buggy output:

=> usb storage
Card did not respond to voltage select!
mmc_init: -95, time 26
No storage devices, perhaps not 'usb start'ed..?

UPSTREAM: blk: Remove various places that do flush cache after read

All these places seem to inherit the codes from the MMC driver where
a FIXME was put in the comment. However the correct operation after
read should be cache invalidate, not flush.

The underlying drivers should be responsible for the cache operation.
Remove these codes completely.
