[MIPS] DBAu1xx0 code style cleanup

Fix several errors and warnings given by checkpatch.pl:

- macros with complex values not enclosed in parentheses;

- leading spaces instead of tabs;

- printk() without KERN_* facility level;

- using simple_strtol() where strict_strtol() could be used;

- line over 80 characters.

In addition to these changes, also do the following:

- initialize variable instead of assigning value later where it makes sense;

- insert spaces between operator and its operands, also remove excess spaces
  there;

- remove unneeded numeric literal type casts;

- remove needless parentheses;

- remove space after the type cast's closing parenthesis;

- insert missing space before closing brace in the array initializers;

- replace spaces after the macro name with tabs in the #define directives;

- remove excess tabs after the macro name in the #define directives;

- fix typos/errors, capitalize acronyms, etc. in the comments;

- make the multi-line comment style consistent with the kernel style elsewhere
  by adding empty first/last line;

- update MontaVista copyright;

- remove Pete Popov's old email address...
