The design of i.MX91 platform is very similar to i.MX93.
Extracts the common parts in order to reuse code.
The mainly difference between i.MX91 and i.MX93 is as follows:
- i.MX91 removed some clocks and modified the names of some clocks.
- i.MX91 only has one A core.
- i.MX91 has different pinmux.
- i.MX91 has updated to new temperature sensor same with i.MX95.

Changes for v5:
- rename imx93.dtsi to imx91_93_common.dtsi.
- move imx93 specific part from imx91_93_common.dtsi to imx93.dtsi.
- modify the imx91.dtsi to use imx91_93_common.dtsi.
- add new the imx93-blk-ctrl binding and driver patch for imx91 support.
- add new net patch for imx91 support.
- change node name codec and lsm6dsm into common name audio-codec and
inertial-meter, and add BT compatible string for imx91 board dts.
Changes for v4:
- Add one imx93 patch that add labels in imx93.dtsi
- modify the references in imx91.dtsi
- modify the code alignment
- remove unused newline
- delete the status property
- align pad hex values
Changes for v3:
- Add Conor's ack on patch #1
- format imx91-11x11-evk.dts with the dt-format tool
- add lpi2c1 node
Changes for v2:
- change ddr node pmu comaptible
- remove mu1 and mu2
- change iomux node compatible and enable 91 pinctrl
- refine commit message for patch #2
- change hex to lowercase in pinfunc.h
- ordering nodes with the dt-format tool
