Description

arm64, riscv: size boot stacks appropriately

In 8db2e8fd16c4 ("Remove the secondary_stacks array in arm64 [...]"),
bootstacks was setup to be allocated dynamically. While this is
generally how x86 does it, it inadvertently shrunk each boot stack from
KSTACK_PAGES pages to a single page.

Resize these back up to the expected size using the kstack_pages
tunable, as we'll need larger stacks with upcoming sanitizer work.
