When CONFIG_OF_LIVE is enabled, dev_of_offset() cannot be used and if used returns an invalid offset. This causes the call to fdt_stringlist_get() in the psci_probe() to fail to read the 'method' property from the PSCI node for the device and hence prevents PSCI from working. Fix this by using the ofnode_read_string() API instead of the fdt_stringlist_get() because this will handle reading the property both when CONFIG_OF_LIVE is enabled or disabled.
Due to the above problem and since commit 81ea00838c68 ("efi_loader: PSCI reset and shutdown") was added, the EFI system reset has been broken for Tegra210 and Tegra196 platforms. This also fixes the EFI system reset for these Tegra platforms.
Oops, just spotted the above typo. Should be Tegra186 and not Tegra196 (which does not exist!). I can correct that.
