x86/boot: Fix -Wint-to-pointer-cast build warning
Fix this warning when building 32-bit with
CONFIG_RANDOMIZE_BASE=y
CONFIG_MEMORY_HOTREMOVE=y
arch/x86/boot/compressed/acpi.c:316:9: warning: \
cast to pointer from integer of different size [-Wint-to-pointer-cast]
Have get_cmdline_acpi_rsdp() return unsigned long which is the proper
type to convert to a pointer of the respective width.
[ bp: Rewrite commit message, touch ups. ]
