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

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 oscillator clock objects will be used to describe the FIRC, FXOSC,
and SIRC clocks, all of which are oscillators on S32CC SoCs.

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.
