Add support for MediaTek MT8189 MMC controller.
According to [1], this is similar to, but not quite the same as
mediatek,mt8196-mmc.

Implement DMA support in the MediaTek MMC driver to enhance data
transfer speed.
- Define DMA control and configuration registers
- Implement functions for starting, stopping, and completing DMA
transfers
- Modify data transfer logic to utilize DMA when enabled
- Ensure proper cache management during DMA operations

Replace separate mask and shift definitions with GENMASK and FIELD_*
macros for better readability and maintainability.
All macros ending in _M have the suffix dropped. The value remains the
same but is now generated with GENMASK. All macros ending in _S are
removed and their uses replaced with FIELD_PREP and FIELD_GET macros.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

The constraints on the MMC_SUPPORTS_TUNING symbol can easily be
expressed in Kconfig (with the addition of SPL_MMC_SUPPORTS_TUNING).
Furthermore, in order to remove <common.h> from the MMC subsystem, the
way this symbol is used today needs to be changed in order to continue
functioning.

With the recent changes on mmc driver, we saw that the boot is ~5 secs
longer compared to v2021.07 on mediatek platforms.
This regression is seen during mmc_init and caused by the following
patch [1].
Indeed since we did not support poll dat0, we fulfilled the condition
of [1] and a delay of 500 ms was added for every __mmc_switch call.
By adding the support of wait_dat0(), we now don't need to mdelay
during mmc_init anymore.

With a 48MHz input clock, the lowest bus frequency can be as low as
48000000 / (4 * 4095) = 2930Hz. Such an extremely low frequency will cause
the mmc framework take seconds to finish the initialization.
Limiting the minimum bus frequency to a slightly higher value can solve the
issue without any side effects.

commit e58e68d9 ("mmc: mtk-sd: assign plat->cfg.f_max with a correct value")
wrongly assumed that plat->cfg.f_max is always unset at the time
mscd_drv_probe() is run. This is not true in case max-frequency being
defined in device tree, as it is then already set by mmc_of_parse()
in msdc_of_to_plat().
Only set plat->cfg.f_max to the default maximum value in case it is
not already set to a sane value.

Currently this driver does not set the value of plat->cfg.f_max, which
results in that MMC framework will always run at the lowest frequency.
This patch sets plat->cfg.f_max to the maximum allowed frequency, which
equals to the source clock frequency.

a value 20 instead.

We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.
Move the compatibility features into a separate header file.

The code is checking for incomplete read when it see the INT_XFER_COMPL
flag, but it forget to first check whether there is anything left in the
FIFO to copy to the RX buffer. This means that sometimes we will get
errors because of erroneous incomplete read operation.
This commit fixes the driver re-ordering the code so that we first
check for data inside the RX fifo and only after check the status
of the INT_XFER_COMPL flag.
