MLK-10976: mxc: sim: Using timer interrupt to implement precise timing.

The EMV4.3 has strict requirement about the reset sequence. The old code use the mdelay, udelay to
achievet, which is not precise enough. Replace it with the timer interrupt. The EMV4.3 requires
40000~45000 clock cycles duration when reset is low.
