arm64: fix stack pointer initialization when CONFIG_STACK_COLORATION
disabled
Add else clause to advance stack pointer (x24) by SMP_STACK_SIZE when
CONFIG_STACK_COLORATION is not defined in ARM64 boot code. Ensures each
CPU's stack is properly skipped in multi-core initialization even when
stack coloration/validation is disabled, preventing stack corruption from
overlapping CPU stacks.
