2018-05-21cpufreq: tegra20: Wrap cpufreq into platform driverDmitry Osipenko1-59/+86
Currently tegra20-cpufreq kernel module isn't getting autoloaded because there is no device associated with the module, this is one of two patches that resolves the module autoloading. This patch adds a module alias that will associate the tegra20-cpufreq kernel module with the platform device, other patch will instantiate the actual platform device. And now it makes sense to wrap cpufreq driver into a platform driver for consistency.

2018-05-21cpufreq: tegra20: Check if this is Tegra20 machineDmitry Osipenko1-0/+4
Don't even try to request the clocks during of module initialization on non-Tegra20 machines (this is the case for a multi-platform kernel) for consistency.

2018-05-21cpufreq: tegra20: Remove unneeded check in tegra_cpu_initDmitry Osipenko1-5/+0
Remove checking of the CPU number for consistency as it won't ever fail unless there is a severe bug in the cpufreq core.

2018-05-21cpufreq: tegra20: Remove EMC clock usageDmitry Osipenko1-22/+0
The EMC driver has been gone 4 years ago, since the commit a7cbe92cef27 ("ARM: tegra: remove tegra EMC scaling driver"). Remove the EMC clock usage as it does nothing. We may consider re-implementing the EMC scaling later, probably using PM Memory Bandwidth QoS API.

The Tegra124 will use a different driver for frequency scaling, so rename the old driver (which handles only Tegra20) appropriately.
