The command is selected on the I/O lines, and further
processing might be done on the DAT lines via the
sd_read_byte() and sd_write_byte() handlers. Since
these methods can't distinct between normal and APP
commands, keep the name of the current command in
the SDState and use it in the DAT handlers. This
fixes a bug that all normal commands were displayed
as APP commands.

in register write, but it is needed in SDMA transfer. e.g. it will be
used in sdhci_sdma_transfer_multi_blocks to calculate boundary_ variables.
Missing this field will cause wrong operation for different SDMA Buffer

Since commit c0a55a0c9d "hw/sd/sdhci: Support big endian SD host controller
interfaces" sdhci_common_realize() forces all SD card controllers to use either
sdhci_mmio_le_ops or sdhci_mmio_be_ops, depending on the "endianness" property.
However, there are device models which use different MMIO ops: TYPE_IMX_USDHC
uses usdhc_mmio_ops and TYPE_S3C_SDHCI uses sdhci_s3c_mmio_ops.
Forcing sdhci_mmio_le_ops breaks SD card handling on the "sabrelite" board, for
example. Fix this by defaulting the io_ops to little endian and switch to big
endian in sdhci_common_realize() only if there is a matchig big endian variant
available.

We use the user_ss[] array to hold the user emulation sources,
and the softmmu_ss[] array to hold the system emulation ones.
Hold the latter in the 'system_ss[]' array for parity with user
emulation.
Mechanical change doing:
$ sed -i -e s/softmmu_ss/system_ss/g $(git grep -l softmmu_ss)

QEMU allows qemu_irq lines to transfer arbitrary integers. However
the convention is that for a simple IRQ line the values transferred
are always 0 and 1. The A10 SD controller device instead assumes a
0-vs-non-0 convention, which happens to work with the interrupt
controller it is wired up to.
Coerce the value to boolean to follow our usual convention.

A64's sd register was similar to H3, and it introduced a new register
named SAMP_DL_REG location at 0x144. The dma descriptor buffer size of
mmc2 is only 8K and the other mmc controllers has 64K.
Also fix allwinner-r40's mmc controller type.

In allwinner_sdhost_process_desc() we just read directly from
guest memory into a host TransferDescriptor struct and back.
This only works on little-endian hosts. Abstract the reading
and writing of descriptors into functions that handle the
byte-swapping so that TransferDescriptor structs as seen by
the rest of the code are always in host-order.
This fixes a failure of one of the avocado tests on s390.
