[PATCH 2/3] spi: bcm63xx-hsspi: return error from failed controller suspend

[Jiawen Liu]

spi_controller_suspend() can fail if the SPI core cannot stop the
controller. bcm63xx_hsspi_suspend() ignored that error, disabled the
PLL and core clocks, and returned success.

Return the suspend error before disabling the clocks.
