[PATCH] arm64: Kconfig: remove unnecessary selection of CRC32

[Eric Biggers]

From: Eric Biggers <ebiggers at google.com>

The selection of CRC32 by ARM64 was added by commit 7481cddf29ed
("arm64/lib: add accelerated crc32 routines") as a workaround for the
fact that, at the time, the CRC32 library functions used weak symbols to
allow architecture-specific overrides.  That only worked when CRC32 was
built-in, and thus ARM64 was made to just force CRC32 to built-in.

Now that the CRC32 library no longer uses weak symbols, that no longer
applies.  And the selection does not fulfill a user dependency either;
those all have their own selections from other options.  Therefore, the
selection of CRC32 by ARM64 is no longer necessary.  Remove it.

Note that this does not necessarily result in CRC32 no longer being set
to y, as it still tends to get selected by something else anyway.

Please consider taking this through the arm64 tree.  But if it doesn't
get picked up there, I'll take it through the crc tree.
