ledc: Add support for esp32h2; Refactor ledc driver clock source selection related code

Browse Source 
LEDC examples and test cases are supported on ESP32H2.
   Switch to use general clock IDs for ledc_clk_cfg_t enum values.
   Deprecate LEDC_USE_RTC8M_CLK.

Note that LEDC_USE_RC_FAST_CLK and LEDC_USE_XTAL_CLK are
non-timer-specific clock sources. You can not have one LEDC timer uses
RTC8M_CLK as the clock source and have another LEDC timer uses XTAL_CLK
RC_FAST_CLK as the clock source and have another LEDC timer uses XTAL_CLK
as its clock source. All chips except esp32 and esp32s2 do not have
timer-specific clock sources, which means clock source for all timers
must be the same one. */
