Subject: [PATCH AUTOSEL 5.6 081/606] ARC: [plat-hsdk]: fix USB regression

From: Eugeniy Paltsev <Eugeniy.Paltsev@...opsys.com>

[ Upstream commit 4c13ca86dcf80a8c705b1f3674ff43d318e970e0 ]

As of today the CONFIG_USB isn't explicitly present in HSDK defconfig
as it is implicitly forcibly enabled by UDL driver which selects CONFIG_USB
in its kconfig.
The commit 5d50bd440bc2 ("drm/udl: Make udl driver depend on CONFIG_USB")
reverse the dependencies between UDL and USB so UDL now depends on
CONFIG_USB and not selects it. This introduces regression for ARC HSDK
board as HSDK defconfig wasn't adjusted and now it misses USB support
due to lack of CONFIG_USB enabled.

Fix that.
