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.

The note /dev/vendor_storage include api to update loader,
this node must config root user access only, but some
project set this node`s owner as bluetooth ,it is a high
risk that the loader data will be corrupted.
Disable this api by default.

.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.
They were converted by:
sed -i "s/supports-emmc;/no-sdio;\n\tno-sd;/g" `grep supports-emmc -rl arch/*`
sed -i "s/supports-sd;/no-sdio;\n\tno-mmc;/g" `grep supports-sd -rl arch/*`

as remove some idle process, shorten delay, remove parsing ext_csd,
remove post-delay for power and so on. All these stuffs are enabled

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.
