Bump Everything to Match new Freedom Repo (#8)

* Bump tool versions

* Use version of OpenOCD which can load programs into flash

* Bump OpenOCD to Handle ISSI Flash Programming

* Update Header files

* add initial support for hifive1

* add dhrystone

* add clock helper functions

* add openocd cfg file

* Demo_GPIO checkpoint -- compiles and runs but no blinky LEDs

* Remove riscv-tests submodule

* Remove FPGA files, as they are no longer relevant to this Repository

* Add openocd_upload script

* Add Pinmux Mappings

Adding the pinmux mappings to the Platform Header

* Add IOF Mappings to platform header

* Re-order the IOF Mapping declarations

* Add more useful things to platform headers

* Get GPIO Demo working again (except interrupts aren't working)

* Update README with more OS packages needed

A bare ubuntu-16.04.1-server installation could not run `make tools`
without these packages.

* bump openocd to get SCKDIV fix

* Remove duplicated help text for run_debug target

* Add package to README that is needed for openocd build

Without this package I was seeing two different failures like below
when running `make tools`.

* Bump OpenOCD to not overwrite SCKDIV when flashing

* Roll back CoreMark
