[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...
