pata_hpt37x: coding style cleanup
Fix 12 errors and 15 warnings given by checkpatch.pl: - *switch* and *case* not on the same indentation level; - no space between *for*/*switch*/*while* and open parenthesis; - space between an unary operator and its operand; - drive blacklist arrays not being *const*; - spaces before tabs; - lines over 80 characters. In addition to these changes, also do the following: - add new line after variable definitions; - fix the style of some multi-line comments.
