Subject: clk: tegra: Register the proper number of resets

From: Thierry Reding <treding@nvidia.com>

commit 5e43e259171e1eee8bc074d9c44be434e685087b upstream.

The number of resets controls is 32 times the number of peripheral
register banks rather than 32 times the number of clocks. This reduces
(drastically) the number of reset controls registered from 10080 (315
clocks * 32) to 224 (6 peripheral register banks * 32).

This also fixes a potential crash because trying to use any of the
excess reset controls (224-10079) would have caused accesses beyond
the array bounds of the peripheral register banks definition array.
