MLK-22210 mxc: emvsim: enable ICM mode 

Once detected a valid TS, the ICM bit is cleared and the data format bit,
IC bit , is set to appropriate value depending on the data format
detected using the initial character.

When TS is 0x3B (direct convention) in cold reset, and then become 0x3F
(inverse convention) in warm reset, it will not in ICM mode.
