DTC introduced an i2c_bus_reg check in v1.4.7, used since Linux v4.20,
which complains about upper case addresses used in the unit name.
nexys4ddr.dts names an I2C device node "ad7420@4B", leading to:
arch/mips/boot/dts/xilfpga/nexys4ddr.dts:109.16-112.8: Warning
(i2c_bus_reg): /i2c@10A00000/ad7420@4B: I2C bus unit address format
error, expected "4b"
Fix this by switching to lower case addresses throughout the file, as is
*mostly* the case in the file already & fairly standard throughout the
tree.
