Andre Przywara fd40ad0d57 sunxi: SPL SPI: Add SPI boot support for the Allwinner H6 SoC
The Allwinner H6 SoC uses a quite different memory map, also changes the
clocks quite a bit. This requires some changes to the SPL SPI routine,
which hardcodes these values so far.

Using the just introduced helper functions to determine base address
and SPI controller generation, we can cover some of these differences
easily.
The clock setup is different, so requires some explicit code changes
there (reset and clock gate in one register at a different address).
Also we need to change the pinmux function to use a different set of
pins that the H6 uses for SPI0.

Eventually we can enable the H6 to use SPI booting in Kconfig.
