Reserve 0x24 bytes at PA 0 for 2nd CPU bootstrap
When we release the reset line for the second CPU, it starts executing code at
physical address 0. boot_secondary() writes a jump instruction at this address.
To ensure that nobody else is using this range, we need to reserve it for this
purpose very early.
We could free up this range later, but it is conceivable that we want to
hotplug the second CPU for power management. In that case, we would need to be
able to take the CPU offline and subsequently take it back online. Hence, we
need to hang on to this range for the entire life of the system.
