spi: fsl-espi: add (un)prepare_transfer_hardware calls to save power if SPI is not in use
Use (un)prepare_transfer_hardware calls to set fsl-espi to
low-power idle if not in use. Reference manual states:
"The eSPI is in a idle state and consumes minimal power.
The eSPI BRG is not functioning and the input clock is disabled"
