apm821xx: 4.14: remove kernel config and patches

This patch removes the 4.14 kernel support from the apm821xx target.
The 4.19 kernel has been available and stable for a while and the 5.4
kernel support has been tested successfully on real hardware as well.

-Subject: [PATCH 15/15] crypto: crypto4xx - block ciphers should only accept
- complete blocks
-
-The hardware automatically zero pads incomplete block ciphers
-blocks without raising any errors. This is a screw-up. This
-was noticed by CONFIG_CRYPTO_MANAGER_EXTRA_TESTS tests that
-sent a incomplete blocks and expect them to fail.
-
-This fixes:
-cbc-aes-ppc4xx encryption unexpectedly succeeded on test vector
-"random: len=2409 klen=32"; expected_error=-22, cfg="random:
-may_sleep use_digest src_divs=[96.90%@+2295, 2.34%@+4066,
-0.32%@alignmask+12, 0.34%@+4087, 0.9%@alignmask+1787, 0.1%@+3767]
-iv_offset=6"
-
-ecb-aes-ppc4xx encryption unexpectedly succeeded on test vector
-"random: len=1011 klen=32"; expected_error=-22, cfg="random:
-may_sleep use_digest src_divs=[100.0%@alignmask+20]
-dst_divs=[3.12%@+3001, 96.88%@+4070]"
