[GSOC-18] Convert PCI drivers to be table driven - Week 7

[Lakhan Shiva Kamireddy]

 Hi All,

As you are aware, my project is to convert PCI drivers to be table driven.
This week I have worked on other PCI drivers. I converted et, ipw, ismt PCI
drivers. I fixed numerous style issues. [1] -[3]

I have added the Plug and Play information for them and found them to be
used by devmatch to match them with modules automatically.
I resolved all build issues.

We have migrated the reviews to Phabricator and see that it is pretty cool.
Phabricator reviews can be found here. [4]-[6]

We need to convert the drivers in a certain way so that kldxref can find it
and record it in linker hints. I am working on PCI drivers so as to make it
easy for kldxref to find them.

In a couple of drivers I have added tables and modified the probe function.
At the same time, I am also learning the internals of the kernel, this will
help our goal ultimately - Automatic module loading. [7]

Please find my updated project homepage here. [8]

Thank you,
Lakhan
