The mmc host controller on the i.mx6q is called usdhc which
is redesigned based on the freescale esdhc controller.
The usdhc controller is almost compatible with esdhc except
it adds one mix register to support debug/SD3.0 and move
the low bit 0-6 of XFERTYP register to the mix control reg
low bit 0-6. Thus on i.mx6q, we have the following compared
with the previous soc: (can refer to RM of chapter 56.3.3)
i.mx6q:
mix control:
bit 31 - bit 7: Added for debug/SD3.0 support
bit 6 - bit 0: move in the XFERTYP register bit 6-0 on previous soc
XFERTYP register:
bit 31 - bit 7: the same as before,
bit 6 - bit 0: no-use
previous soc
mix control: no
XFERTYP register:
bit 31 - bit 0: xfertype information

Pass the GPIO numbers for power and card detect to tegra2_mmc_init(), and
modify that function to perform all required GPIO initialization. This
removes the need for board files to perform these operations.
Move board_mmc_getcd() into tegra2_mmc.c now that the driver knows which
GPIOs to use.
Update affected call-sites in seaboard.c and harmony.c. Note that this
change should make all SD ports work on Harmony, since the required GPIO
setup is now being performed.

The new IO FPGA implementation for Versatile Express contains an MMCI
(PL180) cell with the FIFO extended to 128 words. This causes the
read_bytes() function to go into an infinite loop; as it will wait for
for the half-full signal (SDI_STA_RXFIFOBR) if there are more than 8
words remaining (SDI_FIFO_BURST_SIZE), but it won't receive this signal
once there are fewer than 64 words left to transfer.
One possible fix is to add some build time configuration to change
SDI_FIFO_BURST_SIZE for the new implementation. However, the problematic
code only seems to exist as a small performance optimisation, so the
solution implemented by this patch is to simply remove it. The error
checking following the loop is also removed as this will be handled by
code further down the function.

This patch provides handling of the two way handshake when SEND_OP_COND
(CMD1) is send to mmc card. It is necessary to inform eMMC card if the
host can work with high capacity cards (Jedec JESD84-A441, point 7.4.3).
The extra flag MMC_MODE_HC (high capacity) is added to indicate if the
host is capable of handling the high capacity eMMC cards.
Since this change is added to the generic mmc framework, then it requires
other boards to indicate if their mmc controllers can handle high capacity
cards. As it is now - the old behaviour of the framework is preserved.
