By default extra delay is set to 2000us. When optimizing startup time (!!! Please adjust this value according to the Data Sheet of SPI Flash used in your project.)
In Flash Data Sheet, the parameters that define the Flash ready timing after power-up (minimum
time from Vcc(min) to CS activeare) usually named tVSL in ELECTRICAL CHARACTERISTICS chapter,
and the configuration value here should be:
ESP_SLEEP_WAIT_FLASH_READY_EXTRA_DELAY = tVSL - 900

(For esp32, the delay will be executed in both deep sleep and light sleep wake up flow.
For chips after esp32, the delay will be executed only in light sleep flow, the delay
controlled by the EFUSE_FLASH_TPUW in ROM will be executed in deepsleep wake up flow.)
