soc/tegra: pmc: Fix reset sources and levels

Commit 5f84bb1a4099 ("soc/tegra: pmc: Add sysfs entries for reset info")
added support for reading the Tegra reset source and level from sysfs.
However, there are a few issues with this commit which are ...
1. The number of reset sources for Tegra210 is defined as 5 but it
   should be 6.
2. The number of reset sources for Tegra186 is defined as 13 but it
   should be 15.
3. The SoC data variables num_reset_sources and num_reset_levels are
   defined but never used.

Fix the above by ...

1. Removing the reset source 'AOTAG' from the tegra30_reset_sources
   because this is only applicable for Tegra210.
2. Adding a new tegra210_reset_sources structure for Tegra210 reset
   sources.
3. Correct the number of reset sources for Tegra210 and Tegra186 by
   using the ARRAY_SIZE macro.
4. Updating the functions reset_reason_show() and reset_level_show()
   to check whether the value read is valid. While we are at it
   clean-up these functions to remove an unnecessary u32 variable.
