No. For all other pinctrl clocks there was a corresponding XO_BUFFER 
clock with the similar name (e.g. msm8998_ln_bb_clk3_pin vs 
msm8998_ln_bb_clk3). For qcs404_ln_bb_clk_pin there was no 
qcs404_ln_bb_clk, since the msm8992_ln_bb_clk was used instead (even for 
qcs404).

So for the sake of making the next patch simpler I just rename the 
msm8992 clock to qcs404. I'll add this to commit message.
