at91sam9x5, at91sam9n12, at91sam9g45/m10g45 has plla div2 bits. For other at91 arm926ejs chips, this plla div2 bits (bit-12 in mckr) is reserved and default value after reset is 0. So we can handle all the chip in a same way.

now we can simply remove the chip select macro.

This patch also changes the div2 code to a more readable format.
