r8152: select CRC32 and CRYPTO/CRYPTO_HASH/CRYPTO_SHA256

commit 9973a43012b6ad1720dbc4d5faf5302c28635b8c upstream.

Fix the following build/link errors by adding a dependency on
CRYPTO, CRYPTO_HASH, CRYPTO_SHA256 and CRC32:

  ld: drivers/net/usb/r8152.o: in function `rtl8152_fw_verify_checksum':
  r8152.c:(.text+0x2b2a): undefined reference to `crypto_alloc_shash'
  ld: r8152.c:(.text+0x2bed): undefined reference to `crypto_shash_digest'
  ld: r8152.c:(.text+0x2c50): undefined reference to `crypto_destroy_tfm'
  ld: drivers/net/usb/r8152.o: in function `_rtl8152_set_rx_mode':
  r8152.c:(.text+0xdcb0): undefined reference to `crc32_le'
