ARM: tegra12: clock: Add memory controller clock
Memory controller clock is a child of EMC clock and it is running at
either 1:1 or 1:2 ratio from EMC. MC rate is changing as part of EMC
clock scaling only. No direct MC rate control is allowed.
Added MC clock to the clock tree for information purpose.
Ported from commit 9f8c1aa319ca19a39b56db901326997883fa6f2b
