Add stdout-path property in /chosen node so that earlycon can be
used by just adding earlycon in bootargs.

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.

The PMICs have POWERHOLD set by default which prevents PMIC shutdown
even on DEV_CTRL On bit set to 0 as the Powerhold has higher priority.
So to enable pmic power off this property lets one over ride the default
value and enable pmic power off.

Commit d20f997b4d ("ARM: dts: am57xx-beagle-x15: Remove pinmux
configurations for erratum i869") fat fingered a change in which
basically replaced mmc2_pinctrl_default with mmc1_pinctrl_default. And
kernel dutifully reports conflict of usage.
[...]
pinctrl-single 4a003400.pinmux: pin 4a00376c.0 already requested by
4809c000.mmc; cannot claim for 480b4000.mmc
pinctrl-single 4a003400.pinmux: pin-219 (480b4000.mmc) status -22
pinctrl-single 4a003400.pinmux: could not request pin 219 (4a00376c.0)
from group mmc1_pins_default on device pinctrl-single
omap_hsmmc 480b4000.mmc: Error applying setting, reverse things back
omap_hsmmc 480b4000.mmc: could not initialize pin control state
[...]
But, thanks to the fact that we were in fact setting all the muxes in
U-Boot, all the MMC devices were still properly detected.
Fix the typo.

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.
