[UPSTREAM] arch/arm/imxrt: Improve imxrt_lpi2c_reset

Browse source 
Re-initialize the bus even in the case the bus cannot be re-covered. The
client still has a reference to the bus, and may try to access it again.
If the bus is not initialized or the root clock is off, the access may
cause a crash.
