[v1,0/3] Tegra234 cpufreq driver support

This patchset adds driver support for Tegra234 cpufreq.
Also, added soc data and ops to support multiple SoC's and variants
which have similar logic to {get|set} cpu frequency as Tegra194 in
the same driver.
From cpufreq point, main difference between Tegra194 and Tegra234 are:
 1) Tegra234 uses MMIO for frequency requests and not sysreg like T194.
 2) MPIDR affinity info in Tegra234 is different from Tegra194.
 3) Register bits of pllp_clk_count and core_clk_count are swapped.
So, added ops hooks for Tegra234.

  cpufreq: tegra194: add soc data to support multiple soc
  arm64: tegra: add node for tegra234 cpufreq
  cpufreq: tegra194: Add support for Tegra234
