watchdog: pnx4008: fix warnings caused by enabling unprepared clock
If common clock framework is configured, the driver generates a warning,
which is fixed by this change:
WARNING: CPU: 0 PID: 1 at drivers/clk/clk.c:727 clk_core_enable+0x2c/0xa4()
Modules linked in:
CPU: 0 PID: 1 Comm: swapper Tainted: G W 4.3.0-rc2+ #171
Hardware name: LPC32XX SoC (Flattened Device Tree)
