5150c578fd ledc:add option to put LEDC function into IRAM 
The caches are disabled when reading/writing/erasing flash.
All CPUs should always execute code and access data from internal RAM.
Add an IRAM option to enhance the performance of LEDC.

5070e51dde ledc: Fix two bugs inside LEDC driver 
1. Regression introduced when refactoring on clock sources selection (0d07f859).
   If channel configuration is called before timer configuration on C6, PWM signal may not be able to output.
2. Missing the improper fade parameter fix inside ledc_set_duty_and_update() function.
