spi: spi-s3c64xx: Use module_platform_driver()

Browse source 
subsys_init_call() initializes driver too early.
It's preventing to move DMA channel allocation at the begining
(driver probe).

This patch reduces and simplifies initalization code by
using module_platform_driver() macro.
It's also efficiently delaying driver startup.
