Because of -Werror, this causes a build error.

drivers/mmc: set buswidth and speed before reading data
It should set buswidth and speed of mmc controller before accessing
mmc.

drivers/mmc: make mmc_ext_csd aligned with 16 char
DMA is always used in mmc driver. So the buffer address should
always follow the DMA limitation.
There're same requirement in mmc_read_blocks()/mm

DMA is always used in mmc driver. So the buffer address should
always follow the DMA limitation.
There're same requirement in mmc_read_blocks()/mmc_write_blocks()
on parameter buf. Since parameter buf comes from io_block driver,
it's already handled in io_block driver.
At here, just make the minimum address alignment on 16 chars.

drivers/mmc: fix lba param to int
mmc_read_blocks()/mmc_write_blocks() derived from io_block_ops_t
type. It means that lba param should be integer type, not
unsigned integer type.

drivers/mmc: send CMD8 only for SD card in initialization
Sending CMD8 before CMD1 just causes to fetch data failure in eMMC.
Check whether it's eMMC first. If it's eMMC, send CMD1 command instead.

Add MMC framework
This change is largely based on existing eMMC framework by Haojian Zhuang
(@hzhuang1).
The MMC framework supports both eMMC and SD card devices. It was
written as a new framework since breaking few eMMC framework APIs.
At card probe and after the reset to idle command (CMD0), a Send
Interface Condition Command is sent (CMD8) to distinguish between
eMMC and SD card devices. eMMC devices go through the same
sequence as in the former eMMC framework. Else the framework
uses commands dedicated to SD-cards for init or frequency switch.
A structure is created to share info with the driver. It stores:
- the MMC type (eMMC, SD or SD HC)
- the device size
- the max frequency supported by the device
- the block size: 512 for eMMC and SD-HC and read from CSD
structure for older SD-cards
Restriction to align buffers on block size has been removed.
Cache maintenance was removed and is expected to be done in the platform
or device driver.
The MMC framework includes some MISRA compliance coding style
maybe not yet ported in the existing eMMC framework.
Fixes ARM-software/tf-issues#597
