Clock gates having the CLK_GATE_HIWORD_MASK flag set use the upper 16
bits of the register as a "write enable" mask for the value in the
lower 16 bits.

This adds a clk_gate_flags argument to clock gate creation functions
to allow the introduction of new clock gate modifiers.

This allows us to better detect whether a clk is enabled or not.
- If we can ask a clk, ask it. If it's enabled, go on and ask parents
- If we can't ask it, but it can be enabled, depend on the enable_count.
if it's positive, go on and ask parents
- If we can't ask it and it cannot be enabled, assume it is enabled
and ask parents.
This makes the CLK_ALWAYS_ENABLED unnecessary, since the fixed clk now
always returns 1 in its is_enabled callback.
