[MIPS] Alchemy common code style cleanup

Fix many errors and warnings given by checkpatch.pl:

- use of C99 // comments;

- missing space between the type and asterisk in a variable declaration;

- space between the asterisk and function/variable name;

- leading spaces instead of tabs;

- space after opening and before closing parentheses;

- initialization of a 'static' variable to 0;

- missing spaces around assignement/comparison operator;

- brace not on the same line with condition (or 'else') in the 'if'/'switch'
  statement;

- missing space between 'if'/'for'/'while' and opening parenthesis;

- use of assignement in 'if' statement's condition;

- printk() without KERN_* facility level;

- EXPORT_SYMBOL() not following its function immediately;

- unnecessary braces for single-statement block;

- adding new 'typedef' (where including <linux/types.h> will do);

- use of 'extern' in the .c file (where it can be avoided by including header);

- line over 80 characters.

In addition to these changes, also do the following:

- insert missing space after opening brace and/or before closing brace in the
  structure initializers;

- insert spaces between operator and its operands;

- put the function's result type and name/parameters on the same line;

- properly indent multi-line expressions;

- remove commented out code;

- remove useless initializers and code;

- remove needless parentheses;

- fix broken/excess indentation;

- add missing spaces between operator and its operands;

- insert missing and remove excess new lines;

- group 'else' and 'if' together where possible;

- make au1xxx_platform_init() 'static';

- regroup variable declarations in pm_do_freq() for prettier look;

- replace numeric literals with the matching macros;

- fix printk() format specifiers mismatching the argument types;

- make the multi-line comment style consistent with the kernel style elsewhere
  by adding empty first line and/or adding space on their left side;

- make two-line comments that only have one line of text one-line;

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

- fix/remove obsolete references in the comments;

- reformat some comments;

- add comment about the CPU:counter clock ratio to calc_clock();

- update MontaVista copyright;

- remove Pete Popov's and Steve Longerbeam's old email addresses...
