[MIPS] Pb1200/DBAu1200 code style cleanup
Fix several errors and warnings given by checkpatch.pl:
- use of C99 // comments;
- initialization of a 'static' variable to 0;
- space after opening and before closing parentheses;
- missing space between 'for' and opening parenthesis;
- macros with complex values not enclosed in parentheses;
- printk() without KERN_* facility level;
- unnecessary braces for single-statement block;
- using simple_strtol() where strict_strtol() could be used;
- line over 80 characters.
In addition to these changes, also do the following:
- mention DBAu1200 board in the Makefile;
- replace the group of #include/#ifdef directives by a single
#include <au1xxx.h> since this header contains the needed stuff;
- properly indent the blocks;
- insert spaces between operator and its operands, remove excess spaces
there;
- remove needless parentheses and add some for clarity;
- replace numeric literals/expressions with the matching macros;
- remove space after the type cast's closing parenthesis;
- reduce pb1200_setup_cascade() to the single 'return' statement;
- reduce the number of printed empty lines in the so-called CPLD
workaround;
- remove #undef AU1X00_EXTERNAL_INT since that macro is not defined
anywhere;
- replace spaces after the macro name with tabs in the #define directives;
- remove excess tabs after the macro name in the #define directives;
- fix typo in the BCSR_RESETS_PWMR1mUX macro's name;
- group all Pb1200 PCMCIA definitions together;
- put the function's result type and name/parameters on the same line;
- insert missing and remove excess new lines;
- make the multi-line comment style consistent with the kernel style
elsewhere by adding empty first line and/or adding space/asterisk on
their left side;
- fix typos/errors, capitalize acronyms, etc. in the comments;
- combine some comments;
- update MontaVista copyright;
- remove Pete Popov's old email address...
