board: phytec: imx93: Add phyCORE-i.MX 93 support for all SOM variants
The phyCORE-i.MX 93 is available in various variants (e.g. different ram
sizes, eMMC HS400 yes/no). Enable hardware introspection for the
imx93-phyboard-segin_defconfig, so that during startup the SOM module
variant can be detected, and the hardware can be configured accordingly.
The resulting SPL and u-boot binary shall able to boot each
phyCORE-i.MX 93 module variant on each carrier board. Finally rename
imx93-phyboard-segin_defconfig to imx93-phycore_defconfig, to highlight
its SOM scope.
