spi: bcm63xx-hsspi: disable clocks on resume failure

Browse Source 
bcm63xx_hsspi_resume() enables the HSSPI clock, and optionally the PLL
clock, before restarting the SPI controller queue.

If spi_controller_resume() fails, the function currently reports success
and leaves those clocks enabled. Propagate the error and disable the
clocks before returning.
