MLK-17896: imx: imx7ulp: Update i.MX7ULP SoC and CPU ID

Currently is not possible to call HAB API on i.MX7ULP:

=> hab_status

Secure boot disabled

System is hanging here.

The function is_mx8m() is returning true for i.MX7ULP, thus calling
HAB API with a wrong HAB RVT address.

Align SoC ID and CPU ID with U-Boot upstream to address this issue:
