Code is based on 3.4-rc2

Changes since v8,
	use _relaxed read/write in most place. use writel in operations of Control Register since it needs memory barrier.
	allocate the data for PMECC computation.
	add pmecc prefix for related variable/functions.
	modify code according to J.C's suggestion. except:

		since that will change to: 
		+	for (i = 2, j = 1; i <= 2 * host->cap; i += 2, j = i / 2) {

		why you insist on doing j = i / 2

		you can simplify it by j++

		or loop on j and do i = j << 1;

		it's more simple and faster
