Migrating drivers/usb/host/ohci-lpc32xx.c in U-Boot to DM?

Hey,

As part of migrating more CONFIG symbols to Kconfig, I ran in to drivers/usb/host/ohci-lpc32xx.c not being migrated to DM yet. As the symbols weren't migrated yet, that the deadline for this driver migration was v2019.07 and otherwise enforced in v2021.07 is probably a bit of a surprise here.

The good news is that I believe drivers/usb/host/ohci-da8xx.c is a reasonable template for how the DM conversion should look and it's just needing the probe written and the data structures added. Can someone please look in to doing this conversion? Thanks!
