soc/tegra: pmc: Add reset sources and levels on Tegra194

Browse Source 
Tegra194 supports the same reset levels as Tegra186 but extends the set
of reset sources. Provide custom PMC register definitions to account for
the larger field for the reset sources as well as the updated list of
reset sources.

Changes in v2:
- use the new Tegra194 register definitions
