Subject: [PATCH v3 2/5] ARM: dts: aspeed: yosemite5: Remove ambiguous power
 monitor DTS nodes

Two different power monitor devices, using different drivers, reuse
I2C addresses 0x40 and 0x45 on bus 10 across Yosemite5 board variants.
Defining these devices statically in the DTS can lead to incorrect
driver binding on newer boards when the wrong device is instantiated.

Therefore, remove 10-0040 and 10-0045 device nodes, and let the driver
selection is instead handled in user space by the OpenBMC Entity
Manager based on the actual board configuration.
