[PATCH 1/3] spl: Move all VPL, TPL and PowerPC specific CONFIG options to separate files

Tue May 31 18:17:03 CEST 2022
- Move all PowerPC (and some shared with Layerscape) options to
common/spl/Kconfig.nxp
- Move all other TPL related options to common/spl/Kconfig.tpl
- Move all VPL related options to common/spl/Kconfig.vpl
This makes the whole of common/spl/Kconfig slightly more readable.
