Add a new compatible for the ad3552r variant of the generic DAC IP.

The ad3552r DAC IP variant is very similar to the generic DAC IP,
register map is the same, but some register fields are specific to
this IP, and also, a DDR QSPI bus has been included in the IP.

I am sorry, but what is the product here? It looks like either wrong
order or even completely redundant. What is ad3552r?

And why versions are mixed with real products but without any
compatibility. What does the version express in such case?

dac-ad3552r IP (fpga) is a variant of the dac IP, very similar,
about the version, it still reads as 9.1.b

so i can eventually change it to:

adi,axi-dac-ad3552-9.1.b

Should be more correct.

Best regards,
Krzysztof
