soc: samsung: usi: prevent wrong bits inversion during unconfiguring 



Instead of setting bit 1 (USI_OPTION_CLKSTOP_ON) during USI unconfiguring,
all the other bits in the USI_OPTION register get inverted, which
should not happen as that means the clock will keep getting provided
to the USI IP. Remove the unnecessary tilde.
