This patch does following fixes in MACB ethernet driver for using it on RISC-V systems (particularly QEMU sifive_u machine):
- asm/arch/clk.h is not available on RISC-V port so include it only for non-RISC-V systems.
- Don't fail in macb_enable_clk() if clk_enable() returns -ENOSYS because we get -ENOSYS for fixed-rate clocks.

It seems much better to include an empty header than to ifdef here.
