[ Upstream commit b14e40f5dc7cd0dd7e958010e6ca9ad32ff2ddad ]
Driver is leaking OF node reference on memory allocation failure.
Acquire the OF node reference after memory allocation to fix this and
keep it simple.

Add a reset controller driver for the Canaan Kendryte K210 SoC. This
driver relies on its syscon compatible parent node (sysctl) for its
register mapping. Default this driver compilation to y when the
SOC_CANAAN option is selected.
The MAINTAINERS file is updated, adding the entry "CANAAN/KENDRYTE K210
SOC RESET CONTROLLER DRIVER" with myself listed as maintainer for this
driver.
