arm64: dts: renesas: Add mmc aliases into board dts files

Browse Source 
[ Upstream commit d765a4f302 ]

After the commit 7320915c88 ("mmc: Set PROBE_PREFER_ASYNCHRONOUS
for drivers that existed in v4.14"), the order of /dev/mmcblkN
was not fixed in some SoCs which have multiple sdhi controllers.
So, we were hard to use an sdhi device as rootfs by using
the kernel parameter like "root=/dev/mmcblkNpM".

According to the discussion on a mainling list [1], we can add
mmc aliases to fix the issue. So, add such aliases into Renesas
arm64 board dts files. Notes that mmc0 is an eMMC channel if
available.
