[PATCH v2] i2c: Remove '-Wno-deprecated-declarations' compiler warning

[Sedat Dilek]

This can be dropped with commit 771c035372a036f83353eef46dbb829780330234
("deprecate the '__deprecated' attribute warnings entirely and for good")
now in upstream.

Please, use the kbuild infrastruture to disable compiler warnings.
This should be...

CFLAGS_i2c-core-base.o := $(call cc-disable-warning, deprecated-declarations)

This has the advantage to check if other compilers like GCC support this.

NOTE: My compiler is a prerelease of LLVM/Clang version 7.
