Subject: [PATCH 05/11] ata: replace macro with static inline in libata.h

Avoid a metric ton of sparse warnings like:
drivers/ata/pata_ali.c:176:14: warning: symbol '__x' shadows an earlier one
drivers/ata/pata_ali.c:176:14: originally declared here

Due to nesting min_t macro inside max_t macro which both use a __x
identifier internally.
