To support on-demand booting M33 image from A core. SPL needs to follow M33 kick up sequence to release M33 firstly, then set M33 CPUWAIT signal. ATF will clear CPUWAIT to kick M33 to run. The prepare function also works around the M33 TCM ECC issue by clean the TCM. Also enable sentinel handshake and WDOG1 clock for M33 stop and reset.
