Subject: [PATCH v2 5/5] ARM: dts: AM43xx-epos-evm: DT entries  for ti-usim and phy

- 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.

- i2c2 pinmux configuration -  NxP tda8026 phy is connected to i2c2 lines
