A suggestion from work tglx is currently doing - name the two functions
which manipulate the mask bits 'set' and 'clear' rather than 'enable'
and 'disable'.

Then, the clk ops can do this:

	.clk_enable	= clk_gate_mask_set,
	.clk_disable	= clk_gate_mask_clear,

for ones with positive logic, and:

	.clk_enable	= clk_gate_mask_clear,
	.clk_disable	= clk_gate_mask_set,

for negative logic.  No additional code required, just a variance in data
structure.
