[PATCH] clk: tegra: Fix Tegra210 IQC2 clock lookup

[Karl Mehltretter <kmehltretter@gmail.com>]

gate_clks[] uses tegra_clk_iqc1 for both iqc1 and iqc2. On Tegra210,
gate_clk_init() overwrites the TEGRA210_CLK_IQC1 provider entry with
iqc2 and leaves TEGRA210_CLK_IQC2 unpopulated, so looking up
TEGRA210_CLK_IQC2 fails with -EINVAL.

Use tegra_clk_iqc2 for the iqc2 gate.

Tested on a Jetson Nano 4GB (Tegra210) with a small probe module that
calls of_clk_get_from_provider() on the Tegra210 CAR node. Unpatched,
TEGRA210_CLK_IQC2 (220) returns -EINVAL and TEGRA210_CLK_IQC1 (221)
resolves to iqc2. With this patch on 5b0764a53235, ID 220 resolves to
iqc2 and ID 221 resolves to iqc1.
