[PATCH 2.6.34 1/2] cfi_cmdset_0002.c: Read max timeouts from cfi query data

[PATCH 2.6.34 1/2] cfi_cmdset_0002.c: Read max timeouts from cfi query data

[Markus Niebel]

The max timeouts are coded in the electronic flash data sheet (CFI query
data). Read the timeouts and store them in the chips structure table.
