Fixes for omap variants for v5.5-rc1 cycle

Browse Source 
This series of changes contains fixes for issues recently noticed:
 
 - The ti-sysc interconnect target module driver needs fixes for
   mstandby quirk handling and reset delay
 
 - We need to configure am335x-sancloud-bbe to use rgmii-id mode because of
   the phy changes done earlier
 
 - NET_SWITCHDEV is no longer selected in Kconfig but a dependency and we
   must enable CONFIG_NET_SWITCHDEV to have TI_CPSW_SWITCHDEV
 
 - We are still relying on DEBUG_FS at least for PM configuration, let's
   add it back
 
 - We need to update compatible for am437x-gp/epos-evm because of the
   recent changes to use generic panels
