[U-Boot] [RFC] usb: host: xhci-omap: Remove redundant board_usb_init and board_usb_cleanup functions

[Faiz Abbas]

board_usb_init()/_cleanup() should be in board files and don't have
a place in the xhci-omap driver. Weak versions for
board_usb_init()/_cleanup() already exist in common/usb.c
(for host mode) and drivers/usb/gadget/g_dnl.c (for gadget mode).

Since 1a9a5f7 ("fix double weak board_usb_init functions") the
board_usb_init()/_cleanup() a prefix omap_xhci_* was added to the board
files and in omap-xhci.c because there was a duplicate implementation
in common/usb.c. However, this broke the gadget mode path which uses the
same board_usb_init/cleanup() in the board specific files.

I think a better way would be to just remove the functions from xhci-omap
like in this patch. Any issues with this?
