@brief Detect flash size based on flash ID.
@param chip Pointer to identify flash chip. Must have been successfully initialised via esp_flash_init() @param[out] flash_size Detected size in bytes.
@note Most flash chips use a common format for flash ID, where the lower 4 bits specify the size as a power of 2. If the manufacturer doesn’t follow this convention, the size may be incorrectly detected.
@return ESP_OK on success, or a flash error code if operation failed.
