ASoC: Revert "ASoC: mediatek: Check for error clk pointer"

This reverts commit 9de2b9286a6d ("ASoC: mediatek: Check for error clk
pointer").

With this patch in the tree, Chromebooks running the affected hardware
no longer boot. Bisect points to this patch, and reverting it fixes
the problem.

An analysis of the code with this patch applied shows:

        ret = init_clks(pdev, clk);
        if (ret)
                return ERR_PTR(ret);
...
                for (j = 0; j < MAX_CLKS && data->clk_id[j]; j++) {
                        struct clk *c = clk[data->clk_id[j]];

                        if (IS_ERR(c)) {
                                dev_err(&pdev->dev, "%s: clk unavailable\n",
                                        data->name);
                                return ERR_CAST(c);
                        }

                        scpd->clk[j] = c;
                }

Not all clocks in the clk_names array have to be present. Only the clocks
in the data->clk_id array are actually needed. The code already checks if
the required clocks are available and bails out if not. The assumption that
all clocks have to be present is wrong, and commit 9de2b9286a6d ("ASoC:
mediatek: Check for error clk pointer") needs to be reverted.
