Andy Yan bb0b255fb6 ARM: dts: rockchip: Remove rockchip,default-sample-phase from rk3036.dtsi
This should be a per board property, should not be put in
a soc core dtsi.

And when this property convert from default-sample-phase
in linux-5.7 by commit 8a385eb572 ("ARM: dts: rockchip: fix
rockchip,default-sample-phase property names"), the emmc
on rk3036 kylin board get a initialising error:

[    4.512797] Freeing unused kernel memory: 8192K
[    4.519500] mmc_host mmc1: Bus speed (slot 0) = 37125000Hz (slot req 37500000Hz, actual 37125000HZ div = 0)
[    4.530971] mmc1: error -84 whilst initialising MMC card
[    4.537277] Run /init as init process
[    4.550932] mmc_host mmc1: Bus speed (slot 0) = 300000Hz (slot req 300000Hz, actual 300000HZ div = 0)
[    4.664717] mmc_host mmc1: Bus speed (slot 0) = 37125000Hz (slot req 37500000Hz, actual 37125000HZ div = 0)
[    4.676156] mmc1: error -84 whilst initialising MMC card

I think the reason why the emmc on rk3036 kylin board was able
to work before linux-5.7 was that the illegal property was not
correctly identified by the rockchip dw_mmc driver.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
