Add a clock to the SMMU structure. In the device tree case,
check for a clock node and enable the clock if found.

This patch is dependent upon the following patches that add
a device tree bulk clock function.
"[V6, 1/4] clk: bulk: add of_clk_bulk_get()"
https://patchwork.kernel.org/patch/10583133/
"[V6, 2/4] clk: add new APIs to operation on all available
clocks"
https://patchwork.kernel.org/patch/10583131/
"[V6, 3/4] clk: add managerged version of clk_bulk_get_all"
https://patchwork.kernel.org/patch/10583139/

The clock part is already handled by one of the patch in the
runtime pm series of arm-smmu [1]. This patch should not be needed.
