RustSBI verison 0.3.2

This release version bumps RISC-V SBI specification version to 2.0-rc1. It will include debug console extension and minor SBI 2.0 modifications. Debug Console extension will allow developers to print debug information before their kernel's driver system has initialized; this extension should not be used anymore after drivers loaded.

Developers should note that after RustSBI 0.4.0 release, legacy SBI extensions will no longer be supported. Minor fixes and patches to this version should be applied based on v0.3.2 branch.
