Revient a la config OLED d'origine (20MHz, delais 10ms)

Browse Source 
Le probleme d'affichage etait une panne materielle du module OLED
(probablement du a l'alimentation en 5V testee au debut, hors specs
VDDIO du SSD1322), confirmee par le remplacement du module. Les
contournements logiciels ajoutes pendant le debug n'etaient pas
necessaires.
