zephyr/mpconfigport_minimal: Use MICROPY_CONFIG_ROM_LEVEL_MINIMUM.
This commit adjusts the configuration of the minimal zephyr build to use
MICROPY_CONFIG_ROM_LEVEL_MINIMUM. That's a lot cleaner than explicitly
enabling/disabling options.
Prior to this change the minimal build for qemu_cortex_m3 had size:
Memory region Used Size Region Size %age Used
FLASH: 114436 B 256 KB 43.65%
RAM: 26320 B 64 KB 40.16%
and had the following test results (running using the CI settings, ie
`-d basics float --exclude inf_nan_arith`):
352 tests performed (7092 individual testcases)
352 tests passed
254 tests skipped: ...
With the changes here the qemu_cortex_m3 size is now:
Memory region Used Size Region Size %age Used
FLASH: 99428 B 256 KB 37.93%
RAM: 26312 B 64 KB 40.15%
That's a good decrease of about 15k firmware size. And the test suite
still passes with:
342 tests performed (6776 individual testcases)
341 tests passed
265 tests skipped: ...
