This patch set add USB device controller for the NPCM Baseboard
Management Controllers (BMC).

NPCM UDC driver is a part of the USB ChipIdea driver.

Adding CI_HDRC_FORCE_VBUS_ACTIVE_ALWAYS flag to modify the vbus_active
parameter to active in case the ChipIdea USB IP role is device-only and
there is no otgsc register.

BMC NPCM7XX and BMC NPCM8XX has ten identical NPCM UDC modules,

The NPCM UDC were tested on NPCM845 evaluation board.

Changes since version 3:
 - Add Acked-by Peter Chen.
 
Changes since version 2:
 - Use dev_err_probe.
 - Remove MODULE_ALIAS.

Changes since version 1:
 - Add SoC specific compatible.
 - Remove USB phy mux property from dt-binding, will be handled differently.
 - Add CI_HDRC_FORCE_VBUS_ACTIVE_ALWAYS commit to this patch set.
