This function returns -ENOENT when the property is missing (which the caller
might forgive) and also when the property is present but incorrectly
formatted (which many callers would like to report).

Update the error return value to allow these different situations to be
distinguished.

Since driver model is set up after arch_cpu_init(), that function cannot
use drivers. Add a new arch_cpu_init_dm() function which is called
immediately after driver model is ready, and can reference devices.

This can be used to probe essential devices for the CPU.

These functions currently use a generic name, but they are for x86 only.
This may introduce confusion and prevents U-Boot from using these names
more widely.

In fact it should be possible to remove these at some point and use
generic functions, but for now, rename them.

- Video (HDMI and DisplayPort)
- SATA disk
- Gigabit Ethernet
- SPI flash

USB3 does not work. This may be a problem with the USB3 PCI driver or
something in the USB3 stack and has not been investigated So far this is
disabled. The SD card slot also does not work.

For video, coreboot will need to run the OPROM to set this up.

Some systems have more than 4GB of RAM. U-Boot can only place things below
4GB so any memory above that should not be used. Ignore any such memory so
that the memory size will not exceed the maximum.

This prevents gd->ram_size exceeding 4GB which causes problems for PCI
devices which use DMA.

Commit d3cfcb3e (ARM: DRA7: Enable clocks for USB OTGSS and USB PHY)
changed the member names of prcm_regs from cm_l3init_usb_otg_ss_clkctrl
to cm_l3init_usb_otg_ss1_clkctrl and from cm_coreaon_usb_phy_core_clkctrl
to cm_coreaon_usb_phy1_core_clkctrl in order to differentiate between
the two dwc3 controllers present in dra7xx/am43xx and enabled these
clocks in enable_basic_clocks() in hw_data.c. However these clocks
continued to be enabled in board files/driver files for dwc3 host
mode functionality causing compilation break with few configs.

Fixed it here by making all the clocks enabled in enable_basic_clocks()
and removing it from board files/driver files here.

vbus-usable may not get set if power is provided through both the power barrel
connector and external 5v is also present on the otg connector, at least on
boards where vbus is also controlled through the axp221-pmic.

One way to reproduce this is to bootup an Ippo-q8h board with a usb-host
cable plugged into the otg (so that it will get powered), then unplug the
usb-host cable and plug in a charger, and then do "reset" on the u-boot
console, vbus-usable will then report 0, leading to uboot trying to provide
power to the otg port even though external 5v is present, this commit fixes
this.

When u-boot boots the board may be powering vbus, we turn off vbus in
sunxi_usbc_request_resources, if we are too quick with reading vusb-detect
after this we may see a residual charge and assume we've an external vusb
connected even though we do not. So when we see an external vusb wait a bit
and try again.

Without this when dealing with a pmic controller vbus and doing "reset" on
the u-boot console the musb host will only init once every other boot, because
the other boot it thinks an external vbus is present, this commit fixes this.

On boards which use the pmic to enable/disable vbus on the otg port, the
vbus value is not reset to 0 on reset, as reset only resets the SoC and not
the pmic, so explicitly set vbus to 0 on init (request_resources) by moving
the gpio_direction_output call into request_resources.

For consistency also move the gpio_direction_input call for vbus-detect into
request_resources.
