Subject: [PATCH 0/2] arm64: sl28: fetch the ethernet addresses from its
 EEPROM

After years, NVMEM layouts finally made it into the kernel. The network
devices on the Kontron sl28 boards can now fetch their MAC addresses by
reading the onboard VPD EEPROM. Yay :)

First enable the layout driver (as a module) in the defconfig and then
add the dt fragments.

The second commit was already applied once in commit b203e6f1e833
("arm64: dts: ls1028a: sl28: get MAC addresses from VPD") but had to be
reverted in commit 916508c30e22 ("Revert "arm64: dts: ls1028a: sl28: get
MAC addresses from VPD") because the NVMEM layouts series was dropped.
NVMEM layouts will be included in v6.4, so we can now safely add the
device tree fragments for v6.5.
