dcd/wch: drop toggle-mismatched OUT packets on all USBFS variants
The OUT data-toggle check -- drop a packet whose DATA0/DATA1 doesn't match the
expected toggle (a host retransmit after a lost ACK, or a host that doesn't
alternate the toggle) -- only ran on CH58x. The auto-toggle parts (V103/V20x/V307/
X035) never checked it, so a duplicate/retransmitted OUT was processed twice.
HiFiPhile confirmed it: a host patched to send DATA0-only had CH32V305 accept every
packet. Move the TOG_OK gate out of the CH58x-only block so it runs on every variant;
the manual toggle flip stays CH58x-only. EP0 keeps its own toggle via the SETUP/status
flow and is exempt.
Verified on ci.lan HIL: ch582m_evt (CH58x), ch32v103r_r1_1v0 (V103), nanoch32v203
(V203) all pass.
