This patch adds some delays related to dbop in the lcd and button drivers on the e200v2's. The lcd delay helps avoid the initial "white lcd" failure that has been popping up with the mmu and frequency testing. The Button driver used to have this delay at one point but then I convinced someone to take it out... I think this helps alleviate the space rocks bug at lower pclk settings also but I have not tested that extensively.

I'm thinking it could be a tad bit higher. But if it works hand, you can just commit :)

"I told you so" :D (/me is kidding)
