4f4f85fa0b clk: tegra: Implement memory-controller clock
The memory controller clock runs either at half or the same frequency as
the EMC clock.

3de5bdfb4c clk: tegra: use max divider if divider overflows
When requesting a rate less than the minimum clock rate for a divider,
use the maximum divider value instead of bailing out with an error.
This matches the behavior of the generic clock divider.

[swarren: alloc sizeof(*foo) not sizeof(struct foo), add comments re:
storing pointers to stack variables, make a timeout loop more idiomatic,
use _clk_pll_disable() not clk_disable_pll() from _program_pll() to
avoid redundant lock operations, unified tegra_clk_periph() and
tegra_clk_periph_nodiv(), unified tegra_clk_pll{,e}, rename all clock
registration functions so they don't have the same name as the clock
structs, return -EINVAL from clk_plle_enable when matching table rate
not found, pass ops to _tegra_clk_register_pll rather than a bool.]
