Subject: [PATCH v2] arm64: dts: ls1028a: fix reboot node

The reboot register isn't located inside the DCFG controller, but in its
own RST controller. Fix it.

Fixes: 8897f3255c9c ("arm64: dts: Add support for NXP LS1028A SoC")
Signed-off-by: Michael Walle <[email protected]>
---

changes since v1:
- add fixes tag
- remove "ls1028a-rst" compatible string, because there is no actual
driver for it. It just use the syscon driver.

Hmm, what is your base? It doesn't apply to my branch.
