Commit 0840242e8875 ("ARM: dts: Configure clock parent for pwm vibra")
attempted to fix the PWM settings but ended up causin an additional clock
reparenting error:

clk: failed to reparent abe-clkctrl:0060:24 to sys_clkin_ck: -22

Only timer9 is in the PER domain and can use the sys_clkin_ck clock source.
For timer8, the there is no sys_clkin_ck available as it's in the ABE
domain, instead it should use syc_clk_div_ck. However, for power
management, we want to use the always on sys_32k_ck instead.
