psram-80mhz feature is broken for octal psram.

[liebman]

Enabling psram-80mhz with octal psram (opsram-8m in this case) results in a hang calling ALLOCATOR.init() Removing the psram-80mhz feature works but psram is at 40MHz instead of the wanted 80Mhz.

Hardware: esp32-s3-wroom-1-N16R8

Flashed with: cargo espflash flash --flash-size 16mb --flash-freq 80mhz --monitor --release
the result fails to print "Done" and "Hello World" indicating its not returned from ALLOCATOR.init().
