[PATCH v2 0/8] Refactor imx drivers and introduce support for imx95

[Laurentiu Mihalcea <laurentiumihalcea111@gmail.com>]

From: Laurentiu Mihalcea <laurentiu.mihalcea@nxp.com>

A rather aggressive but arguably much needed refactorization of the SOF
imx drivers. The refactorization is meant to address the code duplication
in the imx drivers and decrease the coding effort required for introducing
a new imx platform.

After refactorization and imx95 introduction, only two drivers remain:
imx8 (meant for the imx8 series: imx8 (imx8qm), imx8x (imx8qxp), imx8m,
and imx8ulp) and imx9 (meant for the imx9 series: imx95 (for now)).

The series also includes the introduction of the imx95 driver.

Changes in v2:

- fixed order of includes in "imx-common.c". They're now sorted
alphabetically.

- use reverse xmas tree ordering for variable declarations.

- add missing call to "of_reserved_mem_device_release()"

- add two new fields: "drv" and "num_drv" in "struct imx_chip_info"

- drop previously obtained R-b's on patches affected by aforementioned
changes.
