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.
