feat(compile): enable PSRAM for esp32p4 with the P4's hex-mode symbols 

The P4 gate ('until the engines validate it') can flip: esp32p4js
v0.3.3 models the AP hex PSRAM + MSPI1 command controller. The classic
SPIRAM chunk emitted S3-era symbols (SPEED_80M, MODE_QUAD/OCT) that do
not exist in the P4's Kconfig.spiram - it gets its own chunk: MODE_HEX
+ SPEED_200M (tree default, rev0-safe; 250M needs rev >= 3). Validated
on staging: an esp_lcd_ek79007 espidf build with psram=enabled boots in
the engine to streaming 1024x600 DSI frames.
