spi: spi-s3c64xx: Fix system resume support Since Linux v4.10 release (commit 1d9174fbc55e "PM / Runtime: Defer resuming of the device in pm_runtime_force_resume()"), pm_runtime_force_resume() function doesn't runtime resume device if it was not runtime active before system suspend. Thus, driver should not do any register access after pm_runtime_force_resume() without checking the runtime status of the device. To fix this issue, simply move s3c64xx_spi_hwinit() call to s3c64xx_spi_runtime_resume() to ensure that hardware is always properly initialized. This fixes Synchronous external abort issue on system suspend/resume cycle on newer Exynos SoCs.
