regulator: spm-regulator: Fix the usage of the 'uV' variable 



The commit 639277b6 ("regulator: spm-regulator: Add additional
settling delay for  FTS2.5 SMPS") incorrectly changed the usage
of 'uV' variable. The local 'uV' variable holds the correct voltage
level to be scaled up/down. Use it instead of vreg->uV.
