clk/zynq/clkc: Add dedicated spinlock for the SWDT
The clk_mux for the system watchdog timer reused the register lock
dedicated to the Ethernet module - for no apparent reason.
Add a lock dedicated to the SWDT's clock register to remove this
wrong dependency.
This does not fix a specific regression but the clock driver was merged
for 3.11-rc1, so best to fix the known bugs before the release.
