clk: ingenic: jz4770: Modify C1CLK clock to disable CPU clock stop on idle
When the main processor goes idle, by default its clock is stopped.
However, this also stops the clock of the co-processor.
clk: ingenic: jz4770: Modify C1CLK clock to disable CPU clock stop on idle
When the main processor goes idle, by default its clock is stopped.
However, this also stops the clock of the co-processor.
Here, if the C1CLK clock is enabled, we disable this functionality.

clk: ingenic: Fix recalc_rate for clocks with fixed divider
Previously, the clocks with a fixed divider would report their rate
as being the same as the one of their parent, independently of the
divider in use. This commit fixes this behaviour.
This went unnoticed as neither the jz4740 nor the jz4780 CGU code
have clocks with fixed dividers yet.

such consistency. The arch/mips/jz4740/clock.c file now contains nothing
more of use & so is removed.
