Fix cast-to-pointer compiler warning

arch/x86/boot/compressed/acpi.c: In function 'get_acpi_srat_table':
arch/x86/boot/compressed/acpi.c:316:9: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
rsdp = (struct acpi_table_rsdp *)get_cmdline_acpi_rsdp();
ÂÂÂÂÂ ÂÂÂ ÂÂÂ ÂÂ ^

Fixes: 41fa1ee9c6d6 ("acpi: Ignore acpi_rsdp kernel param when the kernel has been locked down")
