[PATCH 2/5] soc: tegra: fuse: speedo-tegra210: Update speedo ids

[Aaron Kling via B4 Relay <devnull+webgeek1234.gmail.com@kernel.org>]

From: Aaron Kling <webgeek1234@gmail.com>

Existing code only sets cpu and gpu speedo ids 0 and 1. The cpu dvfs
code supports 11 ids and nouveau supports 5. This aligns with what the
downstream vendor kernel supports. Align the existing supported skus
with the downstream speedo list.

The Tegra210 CVB tables were added in the referenced fixes commit. Since
then, all Tegra210 socs have tried to scale to 1.9 GHz, when the
supported devkits are only supposed to scale to 1.5 or 1.7 GHZ.
Overclocking should not be the default state.

Fixes: 2b2dbc2f94e5 ("clk: tegra: dfll: add CVB tables for Tegra210")
