[nrf fromtree] soc: nordic: common: gppi: Rework sd2ppi_global setup

Rework GPPI configuration for SD^2PPI global domain. There can
be an SoC which does not have dppic135, dppic136, ppib136 and
ppib137 nodes. Add build time conditions to configuration files.

Additionally, remove references to APBxx (bus) names which
could be confusing as they are not references anywhere else.
Use DPPIxxx identification instead.
