I was confused by the comment in esp32/include/soc/soc_caps.h on SOC_GPIO_VALID_GPIO_MASK.
After verifying the mask bits are correct, I have updated the comments for esp32, esp32s2, esp32s3.
I did not check the mask base 0x...FF size.
Not touched because they use a different mask format: esp32c2, esp32c3, esp32c6, exp32h4.
