ARM: dts: dra76x: create a common file with MMC/SD IOdelay data

commit 0651917fe691 ("ARM: dts: dra76x: create a common file with MMC/SD IOdelay data") branch ti-u-boot-2017.01

Add a common device-tree include file with MMC/SD IOdelay data
for DRA76x SoC based on the linux DTSI file.

In the most common case, IOdelay data available in datamanual
can directly be used. This file caters to that common case.

Data is based on DRA76x datamanual, SPRS993A, revised July 2017.

+ * Rules for modifying this file:
+ * a) Update of this file should typically correspond to a datamanual revision.
+ *    Datamanual revision that was used should be updated in comment below.
+ *    If there is no update to datamanual, do not update the values. If you
+ *    need to use values different from that recommended by the datamanual
+ *    for your design, then you should consider adding values to the device-
+ *    -tree file for your board directly.
+ * b) We keep the mode names as close to the datamanual as possible. So
+ *    if the manual calls a mode, DDR50, or DDR or DDR 1.8v or DDR 3.3v,
+ *    we follow that in code too.
+ * c) If the values change between multiple revisions of silicon, we add
+ *    a revision tag to both the new and old entry. Use 'rev11' for PG 1.1,
+ *    'rev20' for PG 2.0 and so on.
+ * d) The node name and node label should be the exact same string. This is
+ *    to curb naming creativity and achieve consistency.
