Support pstore-ramoops for retrieving kernel oops and panics after reboot.

The address and configs are taken from the downstream kernel's device tree.

Downstream doesn't use 0x0 to denote 0.  I am fine with this, if 
someone has a concern or issue with it we can change it before merging.

We could pad this with leading 0's but I find this much easier
to read.

Thank you very much for taking the time to send this.

Hi Zhuowei,

This patch looks good, but I'm unable to find the original patch in my
inbox, at lkml.org or at patchwork.kernel.org. Can you please resend the
original patch to linux-arm-msm@vger.kernel.org, with Kees' R-b and
Jeremy's A-b.

Regards,
Bjorn
