correct SPIRAM settings for ESP32-S3-BOX

[dhalbert]

Fixes #7093 and #6206.

Fix sdkconfig flags for ESP32-S3-BOX SPIRAM. The original flags were wrong in one or more ways, copied from someplace else, I think. I did not try to diagnose each wrong setting, but instead came up with a simpler set.

Note that CONFIG_SPIRAM subsumes ESP32S3_SPIRAM_SUPPORT.
from esp32s3/Kconfig:

    # Hint: to support SPIRAM across multiple chips, check CONFIG_SPIRAM instead
    config ESP32S3_SPIRAM_SUPPORT
        bool "Support for external, SPI-connected RAM"
        default "n"
        select SPIRAM
        help
            This enables support for an external SPI RAM chip, connected in parallel with the
            main SPI flash chip.

Tested by me and also by @PaulskPt, both on a Box.

Thanks. The proof of the pudding is in the eating.

Final feedback: today at 14h20 utc+1, I downloaded from Adafruit's bucketlist file:
adafruit-circuitpython-espressif_esp32s3_box-en_US-20221027-8fe44a2.uf2,
with datetime stamp of creation: 2022-10-27T22:28:31.000Z.
Copied this .uf2 to my ESP32-S3-Box. It works!. CPY statusbar shows 8.0.0-beta.3-24-g8fe44a23d and an IP-address, proving that exists a WiFi connection.
My script (to receive, analyze and display certain airplane flight gps data, from MS Flightsimulator 2020), is working, while the WiFi connection is there. And that was my intention. Thank you Dan, Jepler, Neradoc, MicroDev for your assistence/work to get also this device connecting to WiFi under the current version of CircuitPython. A job well done!!!
