Fix formatting of negative values of type IIO_VAL_FRACTIONAL_LOG2 by
switching from do_div(), which can't handle negative numbers, to
div_s64_rem(). Also use shift_right for shifting, which is safe with
negative values.

This adds a new file, tegra124-jetson-tk1-emc.dtsi that contains
valid timings for the EMC memory clock. The file is included to the
main Jetson TK1 device tree.
