Subject: soc/tegra: pmc: Add reset sources and levels on Tegra194
Git-commit: 48914c4ecb0c0fa1d70ea7b97d758ce5fadacfb0
Patch-mainline: v5.5-rc1
References: jsc#SLE-9391,jsc#SLE-9388,jsc#SLE-10608
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.
