Commit 7945caf22c ("arm: sunxi: Enable SPI/SPI-FLASH support for A64")
selected CONFIG_SPI by default on all Allwinner A64 boards, even though
only 4 out of the 14 A64 boards have a SPI flash chip. All other SoCs
had to manually select DM_SPI and friends, even though they are a
platform property (the sunxi SPI driver is DM_SPI only).
Clean this up to allow easy selection of SPI flash support in U-Boot
proper, by selecting DM_SPI and DM_SPI_FLASH *if* CONFIG_SPI is
selected, for *all* Allwinner SoCs. This simplifies the defconfig for
two Libretech boards already.
Also remove the forced CONFIG_SPI from the A64 Kconfig, instead let the
four boards which allow SPI booting select this explicitly.
Any board wishing to support SPI flash in U-Boot proper now just defines
CONFIG_SPI and CONFIG_SPI_FLASH_<vendor> in its defconfig, Kconfig takes
care of the rest.

Now that those common Allwinner config symbols are defined automatically
for all boards in their Kconfig files, we can remove the now redundant
definitions from the boards' _defconfig files.
Some boards had a differing definiton for some of those symbols, it
looks like mostly to "merge races" when the symbol was introduced (new
board *_defconfig file missed the "add symbol to all files" patch).

The Libre Computer ALL-H3-IT board is a small single board computer that
is roughly the same size as the Raspberry Pi Zero, or around 20% smaller
than a credit card.
The board features:
- H2, H3, or H5 SoC from Allwinner
- 2 DDR3 DRAM chips
- Realtek RTL8821CU based WiFi module
- 128 Mbit SPI-NOR flash
- micro-SD card slot
- micro HDMI video output
- FPC connector for camera sensor module
- generic Raspberri-Pi style 40 pin GPIO header
- additional pin headers for extra USB host ports, ananlog audio and
IR receiver
Only H5 variant test samples were made available, but the vendor does
have plans to include at least an H3 variant. Thus the device tree is
split much like the ALL-H3-CC, with a common dtsi file for the board
design, and separate dts files including the common board file and the
SoC dtsi file. The other variants will be added as they are made
available.
The device tree was synced over from the Linux kernel, along with other
H3/H5 changes, in a previous patch. Thus only the defconfig and an entry
to the MAINTAINERS file is added.
