stmmac: fix kconfig for crc32 build error

stmmac uses crc32 functions so it needs to select CRC32.

Fixes build error:
drivers/built-in.o: In function `dwmac1000_set_filter':
dwmac1000_core.c:(.text+0x3c380): undefined reference to `crc32_le'
dwmac1000_core.c:(.text+0x3c384): undefined reference to `bitrev32'
