crypto: geode-aes - Fix some code style issues

This fixes some code style issues like:

- Use #include <linux/io.h> instead of <asm/io.h> and #include
  <linux/delay.h> instead of <asm/delay.h>

- Use "foo *bar" instead of "foo * bar"

- Add a space after the for or while sentence and before the open
  parenthesis '('

- Don't use assignments in a if condition
