bugzilla: 51796

--------------------------------

[ Upstream commit ea9aadc0 ]

A pre-release silicon erratum workaround where wq reset does not clear
WQCFG registers was leaked into upstream code. Use wq reset command
instead of blasting the MMIO region. This also address an issue where
we clobber registers in future devices.
