clk: move the common clock's to_clk_*(_hw) macros to clk-provider.h to_clk_*(_hw) macros have been repeatedly defined in many places. This patch moves all the to_clk_*(_hw) definitions in the common clock framework to public header clk-provider.h, and drop the local definitions.

clk-divider: make sure read-only dividers do not write to their register Commit e6d5e7d90be9 ("clk-divider: Fix READ_ONLY when divider > 1") removed the special ops struct for read-only clocks and instead opted to handle them inside the regular ops. On the rk3368 this results in breakage as aclkm now gets set a value. While it is the same divider value, the A53 core still doesn't like it, which can result in the cpu ending up in a hang. The reason being that "ACLKENMasserts one clock cycle before the rising edge of ACLKM" and the clock should only be touched when STANDBYWFIL2 is asserted. To fix this, reintroduce the read-only ops but do include the round_rate callback. That way no writes that may be unsafe are done to the divider register in any case. The Rockchip use of the clk_divider_ops is adapted to this split again, as is the nxp, lpc18xx-ccu driver that was included since the original commit. On lpc18xx-ccu the divider seems to always be read-only so only uses the new ops now.

clk: lpc18xx-ccu: fix potential system hang when disabling unused clocks CCU branch clock register must only be accessed while the base (parent) clock is running. Access with a disabled base clock will cause the system to hang. Fix this issue by adding code that check if the parent clock is running in the is_enabled clk_ops callback. This hang would occur when disabling unused clocks after AMBA runtime pm had already disabled some of the clocks.
