[PATCH 4/4] bus: ti-sysc: Fix bogus resetdone warning for cpsw

The cpsw SOFT_RESET register is cleard when out of reset so let's
add SYSS_QUIRK_RESETDONE_INVERTED flag for cpsw. Otherwise we will
get bogus "OCP softreset timed out" warnings on boot.

Fixes: d46f9fbec719 ("bus: ti-sysc: Use optional clocks on for enable and wait for softreset bit")
