mtd: denali: Remove device_info_tag structure
Hi David,
I sent 4 patches using my intel email account. If there is any
problem about the format of these patches, I will resend them after
I arrived at home by using my gmail account, and I will keep on
using gmail account to send patches.
Thanks.

Subject: [PATCH 1/4] mtd: denali: Remove device_info_tag structure.
Most of the variables in this structure are useless, so just
remove this structure and relevant codes.
