Subject: [PATCH v2] clk: sunxi-ng: Fix dependency on SUNXI_CCU_GATE

When CONFIG_SUNXI_CCU is set but no other SUNXI_CCU is selected i got
the following build error:
drivers/built-in.o: In function `ccu_pll_notifier_cb':
drivers/clk/sunxi-ng/ccu_common.c:71: undefined reference to `ccu_gate_helper_disable'
drivers/clk/sunxi-ng/ccu_common.c:73: undefined reference to `ccu_gate_helper_enable'

The problem is the function ccu_pll_notifier_cb in ccu_common.c need
some function from ccu_gate.c which is not compiled since SUNXI_CCU_GATE
is not selected.

This patch remove SUNXI_CCU_GATE and compile ccu_gate.c unconditionnaly
since all other combination of options select SUNXI_CCU_GATE finally.
