[MIPS] Pb1000 code style cleanup

Fix several errors and warnings given by checkpatch.pl:

- use of C99 // comments;

- brace not on the same line with condition in the 'switch' statement;

- printk() without KERN_* facility level;

- unnecessary braces for single-statement block;

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

In addition to these changes, also do the following:

- properly indent the 'switch' statement;

- remove needless parentheses;

- insert spaces between operator and its operands;

- replace numeric literals/expressions with the matching macros;

- remove useless #if dirctive from board_setup();

- remove unneeded numeric literal type casts;

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

- replace spaces after the macro name with tabs in the #define directives, and
  sometimes insert spaces there;

- remove excess new lines;

- 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;

- combine some comments;

- update MontaVista copyright;

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