[redhat] Unify crypto CHACHA20 and POLY1305 configs

Currently CRYPTO_CHACHA20* and CRYPTO_*POLY1305* configs are not in order.
Unify them by merging and moving to configs/common/. Also enable CRYPTO_
CHACHA20POLY1305 on PowerPC as it was done in rhbz#1734711.

Detailed actions taken:

Move:
configs/ark/generic/s390x/zfcpdump/CONFIG_CRYPTO_CHACHA20:CONFIG_CRYPTO_CHACHA20=y
configs/ark/generic/s390x/zfcpdump/CONFIG_CRYPTO_POLY1305:CONFIG_CRYPTO_POLY1305=y
configs/ark/generic/s390x/zfcpdump/CONFIG_CRYPTO_CHACHA20POLY1305:CONFIG_CRYPTO_CHACHA20POLY1305=y
to
configs/common/generic/s390x/zfcpdump/

Delete (per rhbz#1734711):
configs/ark/generic/powerpc/CONFIG_CRYPTO_CHACHA20POLY1305:# CONFIG_CRYPTO_CHACHA20POLY1305 is not set

Delete: configs/pending-common/generic/CONFIG_CRYPTO_POLY1305_NEON:# CONFIG_CRYPTO_POLY1305_NEON is not set
And move:
configs/fedora/generic/arm/aarch64/CONFIG_CRYPTO_POLY1305_NEON:CONFIG_CRYPTO_POLY1305_NEON=m
to:
configs/common/generic/arm/aarch64/CONFIG_CRYPTO_POLY1305_NEON

Merge:
       configs/ark/generic/CONFIG_CRYPTO_NHPOLY1305_NEON:CONFIG_CRYPTO_NHPOLY1305_NEON=m
configs/fedora/generic/arm/CONFIG_CRYPTO_NHPOLY1305_NEON:CONFIG_CRYPTO_NHPOLY1305_NEON=m
to:
configs/common/generic/arm/CONFIG_CRYPTO_NHPOLY1305_NEON

Merge:
       configs/ark/generic/CONFIG_CRYPTO_CHACHA20_NEON:CONFIG_CRYPTO_CHACHA20_NEON=m
configs/fedora/generic/arm/CONFIG_CRYPTO_CHACHA20_NEON:CONFIG_CRYPTO_CHACHA20_NEON=m
to:
configs/common/generic/arm/CONFIG_CRYPTO_CHACHA20_NEON

Merge:
       configs/ark/generic/CONFIG_CRYPTO_NHPOLY1305_AVX2:CONFIG_CRYPTO_NHPOLY1305_AVX2=m
configs/fedora/generic/x86/CONFIG_CRYPTO_NHPOLY1305_AVX2:CONFIG_CRYPTO_NHPOLY1305_AVX2=m
to (depends on X86 && 64BIT):
configs/common/generic/x86/x86_64/CONFIG_CRYPTO_NHPOLY1305_AVX2

Merge:
       configs/ark/generic/CONFIG_CRYPTO_NHPOLY1305_SSE2:CONFIG_CRYPTO_NHPOLY1305_SSE2=m
configs/fedora/generic/x86/CONFIG_CRYPTO_NHPOLY1305_SSE2:CONFIG_CRYPTO_NHPOLY1305_SSE2=m
to (depends on X86 && 64BIT):
configs/common/generic/x86/x86_64/CONFIG_CRYPTO_NHPOLY1305_SSE2

The result:
