[PATCH 4/5] firmware: tegra: bpmp: Add per-SoC EMC clock ID

[Johnny Liu]

The EMC clock ID differs per chip (TEGRA234_CLK_EMC=31,
TEGRA238_CLK_EMC=43, TEGRA264_CLK_EMC=290).

Add an emc_clk_id field to struct tegra_bpmp_soc and set it for
Tegra234, Tegra238 and Tegra264. Tegra186 and Tegra194 have no EMC clock
ID and leave it unset.
