Move this uncommon header out of the common header.

Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.
Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.

Poll for iDMAC TX/RX interrupt before disable DMA.
This to prevent disable DMA before data is transfer
completed.

This patch adds check for command response CRC failure. The driver
is currently ignoring CRC check failure on command resposes which
have CRC atteched to it, which can be potentially dangerous. Even
more grueling problem happens when the command response is followed
by data transfer though, as in that case, the dwmci_data_transfer()
function will spin until it reaches the 240s timeout.

While trying to enable the dw_mmc on rk3188 I managed to confuse
and hang the dw_mmc controller into not delivering further data.
The fifo state never became ready and the driver was iterating in
the while loop reading 0-byte packets forever.
So inspired by how other implementations handle this, check the fifo-
state beforhand and add a timeout to catch any glaring fifo issues
without hanging uboot altogether.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

According to DesignWare TRM, FIFO_COUNT is bit[29:17].
If get the correct fifo_count value, it has to use the FIFO_MASK
as 0x1FFF, not 0x1FF.

There are no places to call these functions.
It should be used the callback function.
Then it can be used as static functions.

Clksel value is exynos specific value.
It removed "clksel_val" into dwmci_host and created the
"dwmci_exynos_priv_data" structure for exynos specific data.

The DMA descriptors used by the DW MMC block must be aligned to cacheline
size, otherwise we are unable to properly flush/inval cache over them and
we get data corruption.
The reason I chose this approach of expanding the structure is because
the driver allocates the descriptors in bulk. This approach does waste
space by inserting slop inbetween the descriptors, but it makes access
to the descriptors easy as the compiler does know the real size of the
structure. It also makes cache operations easy, since the size of the
structure is cache aligned and the structure start address is as well.

The way that struct mmc was implemented was a bit of a mess;
configuration and internal state all jumbled up in a single structure.
On top of that the way initialization is done with mmc_register leads
to a lot of duplicated code in drivers.
Typically the initialization got something like this in every driver.
struct mmc *mmc = malloc(sizeof(struct mmc));
memset(mmc, 0, sizeof(struct mmc);
/* fill in fields of mmc struct */
/* store private data pointer */
mmc_register(mmc);
By using the new mmc_create call one just passes an mmc config struct
and an optional private data pointer like this:
struct mmc = mmc_create(&cfg, priv);
All in tree drivers have been updated to the new form, and expect
mmc_register to go away before long.
Changes since v1:
* Use calloc instead of manually calling memset.
* Mark mmc_register as deprecated.

This patch corrects the divider value written to CLKDIV register.
Since SDCLKIN is divided inside controller by the DIVRATIO value set
in the CLKSEL register, we need to use the same output clock value to
calculate the CLKDIV value.
as per user manual: cclk_in = SDCLKIN / (DIVRATIO + 1)
Input parameter to mmc_clk is changed to dwmci_host, since
we need the same to read DWMCI_CLKSEL register.
This improves the read timing values for channel 0 on SMDK5250
from 0.288sec to 0.144sec
