We should be making it clearer in the DT binding, but this should be
brcm,brcmper-i2c since that was the compatible string added for the DSL

This patch is based on (and targets):
https://github.com/Broadcom/stblinux.git devicetree-arm64/next
V2: Use correct binding that implies 8 B max transfer size. See commit
e2e5a2c61837 ("i2c: brcmstb: Adding support for CM and DSL SoCs")
for details.
