FROMGIT: scsi: ufs: core: Pass target_freq to clk_scale_notify() vop

Browse Source 
Instead of only two frequencies, if OPP V2 is used, the UFS devfreq clock
scaling may scale the clock among multiple frequencies, so just passing
up/down to vop clk_scale_notify() is not enough to cover the intermediate
clock freqs between the min and max freqs. Hence pass the target_freq,
which will be used in successive commits, to clk_scale_notify() to allow
the vop to perform corresponding configurations with regard to the clock
freqs.
