[PATCH] regulator: of: removing two variables min_uV and max_uV

[Saurabh Sengar <saurabh.truth@gmail.com>]

replacing the of_get_property function with of_property_read_u32 function
as its help removing two variables.
also the check for min_uV and max_uV is not required, even if they are
zero and equal we should set apply_uV as true
