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.
