ArmPlatformPkg/PeilessSec: drop _SetSVCMode sequence for Arm
_SetSVCMode sits shortly after _ModuleEntryPoint, to switch into SVC mode
and mask FIQ and IRQ exceptions (making it badly named to boot).
But this should always be the state we start executing in, so most
likely this is another remnant of a time when the edk2 image also
contained Secure Monitor code, which has not been supported for some
time now.
Delete the whole stanza and see if anything breaks.
