[MIPS] Pb1500 code style cleanup

Fix several errors and warnings given by checkpatch.pl:

- use of C99 // comments;

- 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:

- replace numeric literals/expressions with the matching macros;

- insert spaces between operator and its operands;

- properly indent the code and the array initializers;

- remove useless #if dirctive from board_setup();

- remove needless parentheses;

- remove unneeded type casts;

- remove excess new lines;

- make hexadecimal literals all lower case;

- 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,
  also sometimes insert space there for better looks;

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

- update MontaVista copyright;

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