ARM: dts: Drop DTS for BCM59056 PMU
The BCM59056 PMU has its own separate DTSI, meant to be included
in a DTS file after defining the pmu node on some I2C bus.
This seems rather unintuitive; drop the DTS in favor of adding the
BCM59056 PMU node directly into the device DTS files.
If the amount of subdevices supported by the BCM590xx grows, and
a common device tree turns out to be beneficial, it can be reintroduced
in the future.
