[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...
