ata: start separating SATA specific code from libata-core.c
Start separating SATA specific code from libata-core.c:
* move following functions to libata-sata.c:
- ata_tf_to_fis()
- ata_tf_from_fis()
- sata_link_scr_lpm()
- ata_slave_link_init()
- sata_lpm_ignore_phy_events()
* group above functions together in <linux/libata.h>
* include libata-sata.c in the build when CONFIG_SATA_HOST=y
Code size savings on m68k arch using (modified) atari_defconfig:
