Fixes for omaps for various issues noticed during the -rc cycle:

Browse Source 
- Earlier omap4 cpuidle fix was incomplete and needs to use a
   configured idle state instead
 
 - Fix am4 cpsw driver compatible to avoid invalid resource error
   for the legacy driver
 
 - Two kconfig fixes for genpd support that we added for for v5.10
   for proper location of the option and adding missing option
 
 - Fix ti-sysc reset status checking on enabling modules to ignore
   quirky modules with reset status only usable when the quirk is
   activated during reset. Also fix bogus resetdone warning for
   cpsw and modules with no sysst register reset status bit
 
 - Suppress a ti-sysc warning for timers reserved as system timers
 
 - Fix the ordering of clocks for dra7 m_can
