t23x: overlay: Disable c7 cpuidle for safety IGX

Browse Source 
Only c1 (WFI) is needed for safety IGX, so disable the c7 cpuidle
status. As per upstream cpuidle-psci.c driver, the default
archictectural back-end already executes WFI on idle entry, so the idle
driver won't be initialized if only WFI is supported.
