docs: fix review issues in device_issues and README
- Remove duplicate toctree entry for reference/device_issues from docs/index.rst
(already included via docs/reference/index.rst)
- Fix WCH section title: CH32V10X/CH32V20X/CH32V30X → CH32F20x/CH32V20x/CH32V30x
to match the three actual README table entries (CH32F20x, CH32V20x, CH32V305/307)
- Update README anchor links to match the renamed section
- Qualify USBFS non-ISO transfer safety claim: USBHS is protected by
USBHS_INT_BUSY_EN but USBFS behavior is not yet confirmed
- Fix LPC54600 note: "read errata" → "see device issues"
- Remove "totally" from LPC54600 description
