mach-snapdragon: Remove RPMH power domain DT fixup code

Remove the device tree fixup code that was stripping power-domains
properties from device tree nodes. This fixup was a temporary
workaround needed when RPMH power domain driver support was not
available in U-Boot.

Now that RPMH power domain driver support has been added, the power
domain properties can be preserved in the device tree, allowing proper
power domain management. If a suitable power domain driver is not found
for the power-controller node, it will be handled with a warning in
dev_power_domain_ctrl().
