Subject: [PATCH] [ledc] Move require_ledc_iram to config validation

The esp32 to_code runs at PLATFORM priority (1000) before component
to_code at COMPONENT priority (0), so the flag was set too late.
FINAL_VALIDATE_SCHEMA also runs too late for this purpose.
Move to CONFIG_SCHEMA validation to ensure it is set before esp32
processes sdkconfig options.
