Re-enable some features required for the board to still build and the lora driver to run. This board only has 192KB of flash total, so default stm32 build is very close to the limit. Before: LINK build-B_L072Z_LRWAN1/firmware.elf text data bss dec hex filename 184352 68 14112 198532 30784 build-B_L072Z_LRWAN1/firmware.elf (12256 bytes free) After: LINK build-B_L072Z_LRWAN1/firmware.elf text data bss dec hex filename 155028 68 14052 169148 294bc build-B_L072Z_LRWAN1/firmware.elf (41580 bytes free) This work was funded through GitHub Sponsors.
