Include dra74x-mmc-iodelay.dtsi which has pinmux and IODelay
configuration values for the various MMC modes for dra74 SoC
and use it in the pinctrl properties of MMC devicetree
nodes present in am57xx-beagle-x15/am57xx-beagle-x15-revb1.

The dt binding documentation of omap-hsmmc recommends using
"vmmc_aux" for IO supply lines. However
commit 0af28cc926 ("ARM: dts: am57xx-beagle-x15: Add support
for rev B1") added it as "vmmc-aux". Now that anyways it
needs to be fixed, use the generic "vqmmc" binding instead of
the deprecated "vmmc_aux".

According to errata i880 description the speed of Ethernet port 1 on AM572x
SoCs rev 1.1 should be limited to 10/100Mbps, because RGMII2 Switching
Characteristics are not compatible with 1000 Mbps operation [1].
The issue is fixed with Rev 2.0 silicon.
Hence, rework Beagle-X15 and Begale-X15-revb1 to use phy-handle instead of
phy_id and apply corresponding limitation to the Ethernet Phy 1.

Latest update to the BeagleBoard-X15 platform (revision B1)[1] updates
for allowing UHS SD cards to function with the split of supply to SD
card from a dedicated LDO.
As a result of this, AM57xx BeagleBoard-X15 now uses gpio2_30 instead
of gpio6_28 for HDMI because HDMI_LS_OE should now be switched from
GPIO6_28(Y9) to GPIO2_30 (AG8) to avoid a 1.8V GPIO toggling a 3.3V
SoC input when the SD card is in UHS 1.8V mode.
NOTE: For UHS mode to function, we need full fledged IODelay support
in kernel to be functional. IODelay support is yet to be added.
Further, It does not make much sense to spin off a new board
compatible flag since there is no real functional benefit for the
same.
Note: Even though production version is supposed to be B1, there is
over ~200 boards of previous version (A2)[2] out there which continue
to get supported with the existing dts file (to maintain compatibility
with existing bootloaders for A2) and the production board is now
supported as revb1.
