[PATCH] clk: rockchip: don't COMPILE_TEST builds on M68K

[Heiko Stuebner]

Rockchip clock drivers use hash-tables with enums as inputs.

M68K does interesting things in its __hash_32() implementation, casting
that u32 input to an u16 and therefore triggering warnings like:

   drivers/clk/rockchip/clk-rk3528.c: note: in included file (through include/linux/hash.h, include/linux/slab.h):
     arch/m68k/include/asm/hash.h:57:24: sparse: sparse: cast truncates bits from constant value (18720 becomes 8720)
     arch/m68k/include/asm/hash.h:57:24: sparse: sparse: cast truncates bits from constant value (1e8e8 becomes e8e8)

As M68K should never ever need Rockchip clock drivers, simply disable
compile-tests for M68K.
