Subject: ACPI: require CRC32 to build

ACPI: require CRC32 to build

ACPI core now requires crc32() but the kernel build can fail when
CRC32 is not set/enabled, so select it in the ACPI Kconfig entry.

Fixes this build error:

ia64-linux-ld: drivers/acpi/scan.o: in function `acpi_store_pld_crc':
include/acpi/platform/aclinuxex.h:62: undefined reference to `crc32_le'

Fixes: 882c982dada4 ("acpi: Store CRC-32 hash of the _PLD in struct acpi_device")
