cpufreq: ti-cpufreq: add support for AM62L3 SoC
Add CPUFreq support for the AM62L3 SoC with the appropriate AM62L3 speed grade constants according to the datasheet [1]. This follows the same architecture-specific implementation pattern as other TI SoCs in the AM6x family. While at it, also sort instances where the SOC family names were not sorted alphabetically.
