ata: Convert ata_<foo>_printk(KERN_<LEVEL> to ata_<foo>_<level>
Saves text by removing nearly duplicated text format strings by
creating ata_<foo>_printk functions and printf extension %pV.
ata defconfig size shrinks ~5% (~8KB), allyesconfig ~2.5% (~13KB)
Format string duplication comes from:
#define ata_link_printk(link, lv, fmt, args...) do { \
if (sata_pmp_attached((link)->ap) || (link)->ap->slave_link) \
printk("%sata%u.%02u: "fmt, lv, (link)->ap->print_id, \
(link)->pmp , ##args); \
else \
printk("%sata%u: "fmt, lv, (link)->ap->print_id , ##args); \
} while(0)
Coalesce long formats.
