[ Upstream commit 08319adbdde15ef7cee1970336f63461254baa2a ]
The DRM_SIL_SII8620 kconfig has a weak `imply` dependency on EXTCON, which causes issues when sii8620 is built as a builtin and EXTCON is built as a module.
The symptoms are 'undefined reference' errors caused by the symbols in EXTCON not being available to the sii8620 driver.
