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. Signed-off-by: Paul Cercueil <paul@crapouillou.net> Signed-off-by: Stephen Boyd <sboyd@kernel.org>
