Subject: [PATCH v4 2/3] i2c-ocores: sifive: add support for i2c device on 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.
