arm: omap5: tps659038: rename regulator defines

Those regulators don't have any coupling with
what they supply, so remove the suffixes in order
to not confuse anybody.

arm: dra7xx: prcm: add missing registers

some boards might want to use USB1 for host,
without fiddling those registers it'll be
impossible.

usb: phy: omap_usb_phy: fix build breakage

there's no such function usb3_phy_power(),
it's likely that author meant to call,
usb_phy_power() instead, but that's already
called properly from xhci-omap.c.

configs: omap5_common : Boot rootfs from sd card by default

* Since the emmc isn't always programed trying to load the fs from the
  emmc causes boot failures/kernel panic.

* The current bootcmd is set to:
  bootcmd=run findfdt; run mmcboot;setenv mmcdev 1; setenv bootpart 1:2; \
  setenv mmcroot /dev/mmcblk0p2 rw; run mmcboot;

My guess is the env variables should be set so that sd card boot
(dt,kernel,fs) is the default and then fallback to emmc if it fails (no
sd card detected)

The current bootcmd attempts to set mmcroot to the sd card rootfs but
that code doesn't run due to mmcboot being ran early on.

beagle_x15: add board support for Beagle x15

This is the bare minimum support for Beagle x15
into u-boot. There is still quite some work in
order to get this in good shape, but it's a
start.
