[ARM] 4159/1: S3C2410: fix compile of arch/arm/mach-s3c2410/mach-aml5900.c

Fix compile of arch/arm/mach-s3c2410/mach-aml5900.c due to missing
fixes that have been applied to the rest of the tree.

Include <linux/serial_core.h> to provide the upf_t type needed for
the serial code, and remove the old static map of the SPI which is
not needed for the new spi drivers.
