CTCaer 2424ecc4f0 Disable coreboot.rom chainloading for T210B01
Unlike all RCM payloads that are based on hekate's hwinit, coreboot does full power management before sdram init is run.

Because of that and because it doesn't support T210B01, it does not hang as expected and configures all regulators and pins which can be dangerous!
