phy: coding style fixes
The recent patch from Florian Fainelli fixed all 'checkpatch.pl' errors but left the numerous warnings: - including <asm/io.h> instead of <linux/io.h>; - including <asm/uaccess.h> instead of <linux/uaccess.h>; - *extern* declaration in .c file; - block comments using empty /* line; - block comments not starting with * on the middle lines; - block comments not having trailing */ on a separate line; - EXPORT_SYMBOL() not immediately following its function; - unnecessary {} for signle statement block; - spaces before tabs. While fixing these, also fix the following style issues (some of which were found running 'checkpatch.pl --strict'): - alignment not matching open paren; - missing {} on one of the *if* arms where another has them; - use of sizeof(struct structure) instead of sizeof(*variable); - multiple assignments on one line; - empty line before }; - file names in the heading comments; - missing spaces around operators; - no {} around multi-line *if* operator's arm; - unneeded () around subexpressions; - incomplete kernel-doc comment style; - comment line exceeding 80 characters; - missing empty line after declarations.
