clk: zynq: Add dummy clock enable function
A lot of Xilinx drivers are checking -ENOSYS which means that clock driver
doesn't have enable function. Remove this checking from drivers and create
dummy enable function as was done for clk_fixed_rate driver by
commit 6bf6d81c1112 ("clk: fixed_rate: add dummy enable() function").
