esp32: psram_set_cs_timing: sync with esp-idf

[yamt]

Summary

I have no idea what this setting is. I'm just blindly trying to follow whatever esp-idf does.

the esp-idf counterpart: https://github.com/espressif/esp-idf/blob/6e5414b6c4f265a0adfb56a15fbfbe6beb1f8373/components/esp_psram/esp32/esp_psram_impl_quad.c#L702-L712 https://github.com/espressif/esp-idf/blob/6e5414b6c4f265a0adfb56a15fbfbe6beb1f8373/components/esp_psram/esp32/esp_psram_impl_quad.c#L136-L147

Impact

Testing

tested on esp32-devkitc. (no noticeable behavior differences)

Not sure when it got broken, but stm3240g-eval/knxwm fails with

arm-none-eabi-ld: /github/workspace/sources/nuttx/nuttx section `.bss' will not fit in region `ksram'
arm-none-eabi-ld: region `ksram' overflowed by 8 bytes

@tmedicci do you know what difference this difference can make?

I will test it in our internal CI. Please wait to merge it.
