The DWC3 with Innosilicon USB 3.0 PHY on Rockchip platforms
(e.g. rk3328, rk1808) has problem to exit to U0 state from
U1 or U2 state when DWC3 work as peripheral mode. This patch
adds a quirk to reject transition to U1 and U2 state to
workaround this issue.
Refer to commit aaa5c055cc06 ("usb: dwc3: add dis-u1u2-quirk to
reject enter U1 and U2") in Rockchip Linux Kernel-4.4 .

U-Boot has two different variants of dwc3 initializations,
- with dm variant gadget, so the respective dm driver would
call the dwc3_init in core.
- with non-dm variant gadget, so the usage board file would
call dwc3_uboot_init in core.
The driver probe would handle all respective gadget properties
including phy interface via phy_type property and then trigger
dwc3_init for dm-variant gadgets.
So, to support the phy interface for non-dm variant gadgets,
the better option is dwc3_uboot_init since there is no
dedicated controller for non-dm variant gadgets.
This patch support for adding phy interface like 8/16-bit UTMI+
code for dwc3_uboot.
This change used Linux phy.h enum list, to make proper code
compatibility.

Those operations can be used for peripheral operation as well as host
operation.

On rk3399 board, we need to configure phy interface UTMI+ width
to 16 bits via the property "snps,phyif-utmi-bits" of dwc3 node.
But we can't the get the property from kernel dtb. So this patch
initialize the phy interface UTMI+ width in dwc3 platform data,
and not dependent on the property in dtb.

Correct type of varibale base to unsigned long as
keeping it as int causes usb failures if MSB of
the base address is set.

Since interrupt support is not present in u-boot, added an
API to handle the interrupts in dwc3 core. This API can be
polled to handle the interrupts.

Added support for multiple dwc3 controllers. This gives uboot
the capability to control multiple dwc3 controllers.

Added a structure to populate dwc3 core platform data. The board file should
populate these platform data before invoking dwc3 driver.
This will be removed once we have dwc3 driver adapted to use the driver model.
