Subject: [RFC PATCH v1 5/5] ARM: dts: AM43xx-epos-evm: DT entries  for ti-usim

Board specific DT entries for TI's USIM - smart card controller of AM43xx
platfrom.These entries are used by USIM driver for various configurations.

Shutdown line of NXP phy is maped to GPIO5. So enabling same to have support
for NXP phy.
