[Buildroot] [PATCH v3] package/mhz: add new package

[Robert Marko]

mhz is a tool to mathematically calculate the real running CPU frequency
and as such has proved as invaluable tool for developing CPUFreq and
similar features in the kernel.

Its source finally got a license recently so it can be packaged.

I've applied your change, after making a number of tweaks. Many of them
had already been pointed out to you in the review of the previous
versions, but you did not take them into account.

Entry in the DEVELOPERS file was missing.

Missing newline here. This is reported by "make check-package", which
verifies basic coding style details.

Switched to using the "github" helper to do an HTTP download instead.

> +MHZ_LICENSE = MIT/X11

The license is just MIT. X11 is a slightly difference license, and
MIT/X11 is not a valid SPDX identifier.

Missing -D -m 0755 options.

As said: I fixed those small details when applying.

Thanks for your contribution!
