[v2,2/2] {hw/arm,docs/system/arm}: Add SPI to Allwinner A10

Commit Message

Strahinja Jankovic Oct. 1, 2024, 10:13 p.m. UTC

The Allwinner A10 SPI controller is added to the Allwinner A10
description, so it is available when Cubieboard is emulated.

Update the documentation for Cubieboard to indicate SPI availability.
