dts: riscv: lowrisc: Add pwrmgr node to OpenTitan Earlgrey devicetree
Adds the pwrmgr devicetree node. This is a simple binding that holds
only the address of the registers for now.
This patch is part of the OpenTitan watchdog (AON Timer) support patch
series. It is needed to ensure that the watchdog reset functionality
is enabled.
