[PATCH] PCI: Fix general code style



The code style for most files was fixed. This means that blank lines
were added when needed (normally after variable declarations), spaces
before tabs were removed, some code alignment issues were solved, block
comment style was fixed, every instance of "unsigned var" was replaced
with "unsigned int var"... Etc.

This commit does not change the logic of the code, it just fixes
aesthetic problems.
