[PATCH] spi: dt-bindings: sun6i: Add compatibles for A733's SPI controllers

[Jerome Brunet]

The A733 has six SPI controllers with the same IP as the A523.
Like the A523, one of them (spi1) also supports DBI mode.

Add SoC specific compatible strings, falling back to the A523 ones.

Has this been tested? Can someone confirm? We should avoid adding
bindings prematurely, not that it bites us again as it did for the H616
DE bindings, for instance.

Cheers,
Andre

Yes it was. There is SPI-NOR on the cubie A7A. I did a quick sanity
check on it to verify it was functional (writing and reading back).
I should probably have added an note about that.

I have been submit a few changes like one lately. I'm doing that so we
can get on with DT as soon as possible, without waiting on the bindings.

I would normally submit the corresponding DT change at the same time
but DT is currently blocked by the main CCU and pinctrl.
