scsi: ufs: qcom: Pass target_freq to clk scale pre and post change

Instead of only two frequencies, if OPP V2 is used, the UFS devfreq clock
scaling may scale the clock among multiple frequencies. In the case of
scaling up, the devfreq may decide to scale the clock to an intermediate
freq based on load, but the clock scale up pre change operation uses
settings for the max clock freq unconditionally. Fix it by passing the
target_freq to clock scale up pre change so that the correct settings for
the target_freq can be used.

In the case of scaling down, the clock scale down post change operation is
doing fine, because it reads the actual clock rate to tell freq, but to
keep symmetry with clock scale up pre change operation, just use the
target_freq instead of reading clock rate.
