spi_nxp_lpspi: Reset/clock peripheral

If there are HAL definitions available, do these two things:

Ungate the clock for the device from the zephyr driver. Eventually it
would be better to have a clocks property in the LPSPI DT node and get
the resources from there rather than the HAL.

Some platforms require the peripheral to be reset at system level, add
code to do this. Eventually it would be more ideal to have Zephyr
reset drivers for all of the NXP platforms and use DT to describe the
reset resources, but for now we can just do this to get the LPSPI
supported.
