Fix the NO INT in the Multi-BLK IO in SD/MMC, and Multi-BLK read in
SDIO on imx53.

The CMDTYPE of the CMD register (offset 0xE) should be set to "11"
when the STOP CMD12 is issued on imx53 to abort one open ended
multi-blk IO. Otherwise the TC INT wouldn't be generated.

In exact block transfer, the controller doesn't complete the
operations automatically as required at the end of the transfer
and remains on hold if the abort command is not sent on imx53.

As a result, the TC flag is not asserted and SW receives timeout
exception. Set bit1 of Vendor Spec register to fix it.

Add one flag to indicate the GPIO CD/WP is enabled or not
on imx platforms, and reuse the writel/readl as the general
APIs for imx SOCs.

It can be worked around using a GPIO which will be done for i.MX later.

This driver adds basic support for the esdhc-core found on e.g.
imx35/51, as a platform driver.
