Tegra: memctrl: platform setup handler functions
The driver initially contained the setup steps to help Tegra186
and Tegra194 SoCs. In order to support future SoCs and make sure
that the driver remains generic enough, some code should be moved
to SoC.
This patch creates a setup handler for a platform to implement its
initialization sequence.
