Fix PSRAM on espressif ESP32S3 box and box lite

[Neradoc]

Fixes #8128
Use sdkconfig from other ESP32-S3 8MB PSRAM boards.
Tested on Espressif ESP32-S3 Box.

Before:

>>> espidf.get_total_psram()
0

After:

>>> espidf.get_total_psram()
8388608

(No other tests)

@StreakingJerry can you test on the box lite ?

Why doesn't the auto setting work?

[Neradoc]

Good question, turns out it also seems to auto config the PSRAM by only adding:

CONFIG_ESP32S3_SPIRAM_SUPPORT=y

So I'll go with that instead and see what the tests say.

Thank you!
