Replace the dummy implementation of clk_ops.get_rate with a basic
version that only handles the oscillator objects. Subsequent commits
will add more objects to this list.

Initializing all early clocks before the MMU is enabled can impact boot
time. Therefore, splitting the setup into A53 clocks and peripheral
clocks can be beneficial, with the peripheral clocks configured after
fully initializing the MMU.

The DDR clock can be powered by either a PLL or an oscillator. An MC_CGM
mux selects between these two clock sources. A reset block, part of
partition 0, is also connected to this IP block. Therefore, all the
dependencies mentioned above must be configured to have a working clock.

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.

Bring in the implementation for the struct clk_ops->get_parent callback
for the S32G clock driver. The parent is established depending on the
clock object type. Usually, this is determined based on the parent
field, but not always.

Before this change, the internal oscillator clocked the UART with a
frequency of 48MHz. With the necessary support added, the UART clock
rate is increased to 125MHz by changing the clock source from FIRC to
PERIPH PLL PHI3.

Peripheral PLL is one of the platform's PLLs, providing a clock for
peripherals such as UART, QSPI, uSDHC, SPI and CAN. Its source can be
either the FIRC or FXOSC oscillators. It has eight outputs (PHIs) and
their frequencies can be controlled programmatically using output
dividers. An additional output clocks the PERIPH DFS using the VCO
frequency of the PERIPH PLL.

The clock IDs are organized into categories, which are determined based
on the first 2 MSB bits for each ID. Currently, there are two big
categories: hardware and software-defined clocks.
The first category refers to clock IDs understood by the S32CC PLL muxes
and MC_CGM module muxes and is immutable. The last category of the
clocks includes software-defined IDs for clocks to allow an easy
representation of the hierarchy.
