Add the low-level implementation to enable the ARM PLL oscillator, which
is disabled by default when booting the SoC. It will be used by PLL
diviers, for which support will be added later.

The clock muxes will simply pass the set rate request to the clock
module connected to its source, as they do not alter the frequency.

Add set rate support for fixed divider clock modules of whose role is to
reduce the source frequency by a factor.

On S32CC SoCs, the set_parent operation will be used on clock modules
that are mux instances in order to establish the clock source. This will
be used for PLLs and MC_CGM muxes.

s32cc_init_early_clks will be used to increase the frequency of the
clocks which have a performance impact on BL2 boot. This set includes
A53, XBAR, DDR and Linflex clocks. For now, it will only contain the
frequency set for FXOSC. More clock management will be added in the next
commits.

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.

The S32CC is an umbrella for S32G2, S32G3 and S32R45 SoCs; therefore,
this clock driver will be used for all of these families.
