PX30_GRF_SOC_CON5 is intended for postponing the auto switch
of pinmux from SDMMC to JTAG after removing the SD cards.
However, the default value is too small to meet the actual
requirement. Increase this value to 5 seconds currently.

.set_ios() is called from .resume() as well. For SDIO device which sets
keep-power-in-suspend, nothing should be changed after resuming, as well
as sample tuning value, since this value is tuned already. So we should
not overwrite it with the default value.

supports-* stuff were used for rockchip platforms to speed up booting
if we know what exactly the host was used for. As we have upstreamed all
these with some very similar ways, now it's the time we migrate our dts
files to use new properties.

We observed the failure of initializing card after resume
accidentally. It's hard to reproduce but we did get report from
the suspend/resume test of our RK3399 mp test farm .Unfortunately,
we still fail to figure out what was going wrong at that time.
Also we can't achieve it by retrying the host->f_init without falling
back it. But this patch will solve the problem as we could add some log
there and see that we resume the mmc card successfully after falling
back the host->f_init. There is no obviousside effect found, so it seems
this patch will improve the stability.

v2 tuning will inherit pre-stage loader's phase
settings for the first time, and do re-tune if
necessary. Re-tune will still try the rough degrees,
for instance, 90, 180, 270, 360 but continue to do the
fine tuning if sample window isn't good enough.

The ROM code for Rockchip platform never support detecting
SD 3.0 mode, so if the SD card contains system image running
into SD 3.0 mode in kernel, it will fails to reboot.
The problem is SD 3.0 mode is using 1.8V signal and could only
be switched back into 2.0 mode by power cycle. If the customed
board could not switch off its power rail, the ROM code can't
soft reset the SD.
Add mmc_sd_shutdown to workaround this special case and don't
bother normal SD cards used as external disk by checking the
RESTRICT_CARD_TYPE_MMC flag.

According to commit 736706bee3 ("get rid of legacy 'get_ds()' function")
Every in-kernel use of this function defined it to KERNEL_DS (either as
an actual define, or as an inline function). It's an entirely
historical artifact, and long long long ago used to actually read the
segment selector valueof '%ds' on x86.
Which in the kernel is always KERNEL_DS.
Inspired by a patch from Jann Horn that just did this for a very small
subset of users (the ones in fs/), along with Al who suggested a script.
I then just took it to the logical extreme and removed all the remaining
gunk.
Roughly scripted with
git grep -l '(get_ds())' -- :^tools/ | xargs sed -i 's/(get_ds())/(KERNEL_DS)/'
git grep -lw 'get_ds' -- :^tools/ | xargs sed -i '/^#define get_ds()/d'
plus manual fixups to remove a few unusual usage patterns, the couple of
inline function cases and to fix up a comment that had become stale.
The 'get_ds()' function remains in an x86 kvm selftest, since in user
space it actually does something relevant.
