-Incorporate review comments from Andrew
-Extend dt bindings into i2c-ocores.txt instead of adding new file
-Rename SIFIVE_FLAG_POLL to OCORES_FLAG_BROKEN_IRQ
V1:
-Update dt bindings for sifive i2c devices
-Fix broken
OCORES_FLAG_BROKEN_IRQ is particularly for
FU540-COOO SoC.
The polling function identifies a SiFive device based on the device node
and enables the workaround.
