[ Upstream commit ac08bda1569b06b7a62c7b4dd00d4c3b28ceaaec ]
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.
