Log Message:
Avoid undefined behavior of signedness bit shift in ahcisata_core.c

sys/dev/ic/ahcisata_core.c:365:31, left shift of 1 by 31 places cannot be represented in type 'int'
sys/dev/ic/ahcisata_core.c:558:16, left shift of 1 by 31 places cannot be represented in type 'int'

Detected with Kernel Undefined Behavior Sanitizer.

This code could be refactored in future and switched to ISSET(9) API,
instead of reinventing the common functionality.
