MXSCM-244 mx6dqscm: adjust drive strength for scm i.mx6dq parts
From experimentation a DSE value of 60ohms shows better results for
both 2GB and 1GB MXDQSCM parts. The failure rate part using the memtest
improves using this value for DSE. This adjusment is performed in the
corresponfing imximage_scm_lpddr2.cfg file.
