The current way of specifying Arm configuration options is insufficient
since we can't identify the SoC we're building for from the MIDR
information.

Instead use user input - the machine meson option to specify the SoC, e.g.:
meson soc_test -Dmachine=thunderx
meson soc_test --cross-file config/arm/thunderx/arm64_thunderx_linux_gcc

We also want to be able to disable which drivers (and possibly
libraries) are built without user input. This is useful when building:
1. on an SoC that is slow and we want to build only what is necessary
without the user having to check which libraries they have installed
2. a cross build on a fast aarch64 machine but with target SoC which
differs in capabilities or libraries.

  build: rework Arm build options
  build: disable drivers from file
