Subject: [PATCH 4.20 24/50] MIPS: Use lower case for addresses in nexys4ddr.dts

4.20-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Paul Burton <paul.burton@...s.com>

commit 047f2d941b8b24cadd6a4a09e606b7f41188ba3e upstream.

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@...00000/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.
