CFI MinorVersion 5 with P33 Strataflash

Hi,

I'm using Intel's Strataflash RC48F440090TB00 on an IXP465 and found that this chip is returning a CFI MinorVersion of 5 which makes read_pri_intelext return an error in cfi_cmdset_0001.c and prevent flash detection.

The following patch is a workaround for this issue but I didn't find any reference to this value of CFI MinorVersion, even in the datasheet (which may not be up to date as P33 should be only the full 3V3 version of P30).

After this change he flash is properly detected and everything is fine with all the MTD layer.
