[PATCH v2] sh: Use generic OHCI platform provider symbol

[Karl Mehltretter]

From: Pengpeng Hou <pengpeng@xxxxxxxxxxx>

The old SuperH-specific `USB_OHCI_SH` provider symbol no longer carries
an OHCI provider object.  The current platform OHCI provider is
`USB_OHCI_HCD_PLATFORM`, which builds ohci-platform.o.

Several SH CPU subtypes still select `USB_OHCI_SH`, and the
sh7757lcr defconfig still enables it directly.  Switch both the subtype
selects and the defconfig to `USB_OHCI_HCD_PLATFORM` so the intended OHCI
provider remains reachable when `USB_OHCI_HCD` is enabled.

Fixes: 4f6dfc2136fb ("usb: remove the dead USB_OHCI_SH option")

Resend of Pengpeng's patch from June, which Geert reviewed but which
never got applied. Geert asked for it to be picked up instead of my
"sh: Drop the selects of the removed CONFIG_USB_OHCI_SH symbol", which
is withdrawn:

Changes since v1 (https://lore.kernel.org/r/20260624081926.12426-1-pengpeng@xxxxxxxxxxx/):
- rebased on current mainline so that git am applies it
- Fixes: tag as suggested by Geert, his Reviewed-by collected
- checked with make ARCH=sh sh7757lcr_defconfig and an SH7720 config
  with USB_OHCI_HCD, ohci-platform.o builds with sh4-linux-gnu-gcc
