PN532 RFID module consumes too much power when ESP is in deep sleep

The problem

When I put the board on deep sleep (e.g,: deep_sleep.enter), PN532 chip can be left in a state where it consumes too much power (around 20 - 40 mA). I have traced the issue to the fact that, before entering deep sleep, the chip is not properly powered down and can be left with the RF field on waiting for a tag.

Example YAML snippet

i2c:
  scl: GPIO32
  sda: GPIO33
  scan: True
  frequency: 100kHz
  timeout: 10ms

pn532_i2c:
  update_interval: 1s
  id: rfid
  on_tag:
    then:
      - binary_sensor.template.publish:
          id: tag_present
          state: ON
      - delay: 1s
      - binary_sensor.template.publish:
          id: tag_present
          state: OFF

binary_sensor:
  - id: tag_present
    platform: template
    name: RFID tag present

deep_sleep:
  id: sleeper
  touch_wakeup: false
  esp32_ext1_wakeup:
    pins: [GPIO39, GPIO35, GPIO14]
    mode: ANY_HIGH

button:
  - id: button_sleep
    platform: template

    on_press:
      then:
        - deep_sleep.enter:
            id: sleeper

Anything in the logs that might be useful for us?

No response

Additional information

I will link a PR tested with I²C, but will probably work with SPI as well.
