The arasan SDHCI driver doesn't use MMC tuning but SDHCI tuning. Both
are not supported yet in barebox.
Add SDHCI tuning support from linux v6.7.

Linux uses a different sdhci_wait_idle function than what barebox
currently does. For HS200 support, the linux version needs to be used.
As currently only arasan-sdhci is tested with HS200, keep the old
sdhci_wait_idle as sdhci_wait_idle_data and convert all users of it.

Depending on the used SDHCI mode the clock phases are different.

HS200 is a timing mode for eMMCs to work 8bit with 200MHz clocks.
To be used, drivers need to set the correct drive strength, clock phases
and then SDHCI can start tuning for HS200.

The timings are used to check if mci_host->timing is equal to one of

This series adds support for HS200 mode to mci-core and sdhci.
As the host driver also needs to handle clock setup, pin control and
host specific tuning, this series only adds HS200 support to the Arasan
SDHCI driver.
Tested on: ZynqMP
Compile tested: for ZynqMP with/without CONFIG_MCI_TUNING
Read and register the sampleclk and sdcardclk. They are needed later for
HS200 tuning support.

Hi All,
I am happy to announce barebox-2024.03.0.
This release brings us runtime partitioning support. We have a new command
that allows us to create new partition tables and to manipulate existing
partition tables. Also the partition tables are now reparsed when
partitions have changed.
