[RFT][PATCH 1/2] spi: s3c24xx: Add missing spi_master_{resume,suspend} calls to PM callbacks

[Axel Lin <axel.lin-8E1dMatC8ynQT0dZR+AlfA@public.gmane.org>]

This is required since commit 2025172e3280 "spi/bitbang: Use core message pump".
spi-bitbang now uses core message pump, so it needs to call spi_master_suspend/
spi_master_resume to start/stop the queue while suspend/resume.
