clk: tegra: annotate struct tegra210_clk_emc_provider with __counted_by_ptr
Annotate the "configs" pointer field of "struct
tegra210_clk_emc_provider" with the "__counted_by_ptr" attribute,
allowing the compiler to perform runtime bounds checking on accesses to
"configs" based on the value of "num_configs".
The "emc->provider.configs = devm_kcalloc(...)" call uses
"emc->num_timings" for the number of elements, which is then assigned to
"emc->provider.num_configs" before any accesses to "configs". The
"num_configs" field isn't modified after assignment.
