There are no external users of the vsc7514_*_regmap[] symbols or
vsc7514_vcap_* functions. They were exported in commit 32ecd22b ("net:
mscc: ocelot: split register definitions to a separate file") with the
intention of being used, but the actual structure used in commit
2efaca41 ("net: mscc: ocelot: expose vsc7514_regmap definition") ended
up being all that was needed.

Bury these unnecessary symbols.
