ARM: dts: msm: Enable UFS force probe for SDM710 CDP platform

SDM710 can support both UFS device and eMMC device. And there is
a requirement to support both on a given platform. But if UFS is
not a bootdevice it won't get probed. So enable "force-ufshc-probe"
property for ufs probe to happen even though its not a bootdevice.

Both eMMC & UFS can be supported only on CDP, since only CDP has the
provision to support external eMMC/UFS cards besides internal eMMC
/UFS. So enable force-probe flag only for CDP platform.
