picosoc: enable fast multiply option for icebreaker
...
This patch splits the picosoc's `ENABLE_MULDIV` paramter
into `ENABLE_MUL`, `ENABLE_DIV` and `ENABLE_FAST_MUL`,
and also enables the DSP-based fast multiplier for
the iCE40up5k icebreaker board.

Enable the use of 64-bit riscv tools
...
Many Linux distributions now include the tools for RISC-V (for example
Ubuntu 20.04 has gcc-riscv64-unknown-elf) but in order for
make TOOLCHAIN_PREFIX=riscv64-unknown-elf-
to work we need to be explicit about compiling for 32-bit.
