MLK-12358: ARM: dts: imx7d-val-m4: disable sim1 and reg_can2_3v3

- Disable the sim1 on imx7d val board, because that there
are pin conflictions between sim1 and flexcan2 used by M4.
- Disable can2 is not enough, since the reg_can2_3v3 will be
turned off by the regulator framework and that will impact
can2 in m4 side even if can2 driver disabled in A7 side.
