If the regulator is already enabled, this happens if the regulator
is set in regulator-always-on, regulator_set_enable() return -EALREADY.
Ignore the -EALREADY return since it's not an error.

Add support for the Libre Computer aml-s905d3-cc "Solitude" board:
https://libre.computer/products/aml-s905d3-cc/
The Solitude board has a Credit Card form factor, similar to the
the previous "Le Potato" card, but with the Amlogic A311D SoC,
MIPI DSI and CSI connectors. PoE header and a single USB2 Type-C
connector replacing the microUSB one for power and USB 2.0.
The board has an embedded SPI NOR flash, and EFI Capsule support
is added.
The GUID is dynamically generated for the board, to get it:

The link_startup_again logic was added in Linux to handle device
that were set in LinkDown state, which should not be the case since U-boot
doesn't set LinkDown state are init, and Linux sets the device active
in ufshcd_init() for the first link startup.
ufshcd_set_ufs_dev_active(hba) is called at ufshcd_init() right before
scheduling an ufshcd_async_scan that will call ufshcd_device_init() then ufshcd_link_startup().
The comment in probe says:
/*
* We are assuming that device wasn't put in sleep/power-down
* state exclusively during the boot stage before kernel.
* This assumption helps avoid doing link startup twice during
* ufshcd_probe_hba().
*/
we can assume the same from U-Boot.
While it worked to far, it breaks link startup for Qualcomm Controllers v5,
let's just remove the logic.

There is no need to flush and invalidate all data updated by the
driver, mainly because on ARM platforms flush also invalidates
the cachelines.
Split the function in two and add the appropriate cacheline
invalidates after the UFS DMA operation finishes to make sure
we read from memory.
Flushing then invalidating cacheline unaligned data causes data
corruption issues on Qualcomm platforms, and is largely unnecessary
anyway, so let's cleanup the cache operations.

This switches all boards with the Allwinner H616/H618/H313/H700 SoCs over to
use OF_UPSTREAM. We are doing it for this SoC family only since the DTs
between the U-Boot and the kernel repo are exactly identical, whereas other
families have one compatibility fix in U-Boot to allow booting older kernels.
Other will follow if this plays out well.
The biggest chunk otherwise is adding support for an Anbernic game console,
using the H700 SoC. For that we need to enhance the DRAM support code, and
pick two DT commits from the mainline kernel/DT rebasing repo, followed
by the defconfig patch.
On top of that two small fixes for the old Allwinner A80.
Gitlab CI passed, and I booted that briefly on some boards, including an
H616 and an H618 one (with LPDDR4).
