feat(nxp-clk): add partitions objects

The S32CC-based SoCs are organized in partitions. These are
software-resettable domains in which configuration participates in
MC_CGM, MC_ME, and RDC modules. A partition is an island that may
contain multiple blocks, each of which corresponds to a peripheral or a
core and can, in most cases, be reset individually. This reset structure
results in better device availability. If a fault is detected in a
software reset domain, that domain can be reset separately without
impacting the operation of the rest of the chip.

their frequencies can be controlled programmatically using output
dividers. An additional output clocks the PERIPH DFS using the VCO
frequency of the PERIPH PLL.
