Jörg Thalheim 688ee555de refactor(nxp): parameterize i.MX platform builders to reduce duplication
This refactoring reduces code duplication across i.MX93, i.MX8MP, and
i.MX8MQ platforms by extracting common build logic into parameterized
shared builders. This makes it easier to maintain and add new i.MX
platforms while ensuring consistency across all platforms.
