ARM: dts: Drop DTS for BCM59056 PMIC

The BCM59056 PMIC has its own separate DTSI, meant to be included
in a DTS file after defining the pmu node on some I2C bus.

I'm not aware of any other device that does this, and it seems very
unintuitive. Drop the DTS in favor of adding the BCM59056 PMIC node
directly into the device DTS files.
