ata: move ata_eh_analyze_ncq_error() & co. to libata-sata.c

Browse source 
* move ata_eh_analyze_ncq_error() and ata_eh_read_log_10h() to
  libata-sata.c

* add static inline for ata_eh_analyze_ncq_error() for
  CONFIG_SATA_HOST=n case (link->sactive is non-zero only if
  NCQ commands are actually queued so empty function body is
  sufficient)

Code size savings on m68k arch using (modified) atari_defconfig:
