bcma: move parallel flash support to separated file
This follows the way of handling other flashes and cleans code a bit. As next task we will want to move flash code to ChipCommon driver as: 1) Flash controllers are accesible using ChipCommon registers 2) This code isn't MIPS specific This change prepares bcma for that.
