[ Upstream commit b96e9eb62841c519ba1db32d036628be3cdef91f ]
Current clock name looks like this:
/soc/bus@ffd00000/pwm@1b000#mux0
This is bad because CCF uses the clock to create a directory in clk debugfs.
With such name, the directory creation (silently) fails and the debugfs
entry end up being created at the debugfs root.
With this change, the clock name will now be:
ffd1b000.pwm#mux0
This matches the clock naming scheme used in the ethernet and mmc driver.
It also fixes the problem with debugfs.
Fixes: 36af66a79056 ("pwm: Convert to using %pOF instead of full_name")
