From: Duncan Ma <Duncan.Ma@xxxxxxx> [WHY] Implement changes to transition from Pre-OS odm to Post-OS odm support. Seamless boot case is also considered. [HOW] Revised validation logic when marking for seamless boot. Init resources accordingly when Pre-OS has odm enabled. Reset odm and det size when transitioning Pre-OS odm to Post-OS non-odm to avoid corruption. Apply logic to set odm accordingly upon commit.
