Subject: [PATCH] mcu/fe310: Update to stock compiler

Previously riscv64-unknown-elf toolchain from SiFive was used.
Now there is commonly available version.
Unfortunately it does not have required option icsr enabled.

This adds -march=rv32imaczicsr to compiler while keeps
-march=rv32imac for linker to be able to used default libraries.
