… (#9847)

Kernel 6.18 stable progressed past 6.18.18 (last patch rewrite baseline,
commit 2dc5b23) and refactored dwc3_readl()/dwc3_writel() to take the
struct dwc3 pointer directly instead of dwc->regs. The patch context
still referenced dwc->regs, causing hunks #1 (at core.c:153) and #3
(at core.c:213) to fail on builds against 6.18.32.

Update the patch context to drop "->regs" (no change to the +/- payload)
so it applies cleanly on 6.18.32 while remaining compatible with the
prior baseline.

Verified with patch -p1 --dry-run against the 6.18.32 HEAD blob from the
linux-rockchip 6.18 branch: exit 0, all 16 hunks across the 3 files
apply (offset -2 on core.h, harmless).
