cpufreq: ti-cpufreq: add support for AM62L3 SoC

Browse Source 
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.
