i2c: ocores: add support for i2c device on Sifive FU540-c000 SoC
Update device id table for Opencore's I2C master based re-implementation
used in FU540-c000 chipset on HiFive Unleashed platform.
Device ID's include Sifive, soc-specific device for chip specific tweaks
and sifive IP block specific device for generic programming model.
