Modify LEDC driver 1. configure LEDC timer saparately 2. add peripher_crtl.c/.h To enable the peripheral modules, we have to set/clear the control register in dport_reg.h. These bits are disabled by default and they are all in a same register, so we need to add a lock on that. 3. add include esp_err.h in gpio.h
