[Ovmsdev] PSRAM fix in esp-idf release v3.3

Mark, it seems the fix has finally arrived in the official release 3.3 branch: https://github.com/espressif/esp-idf/issues/2892#issuecomment-658327913 https://github.com/espressif/esp-idf/commit/f4333c8e3a554e8bb4210d825cbdf4bc... Btw:

In the v3 silicon, the issue has been fixed, and the workaround is no longer required.

I guess that means from some manufacturing point on we should provide two builds, one for the older hardware and one for the modules with v3 chips, as the fix definitely has a performance impact.
