This patch enables configs for Trusted Execution Environment(TEE) and
Open Portable Trusted Execution Environment(OP-TEE).

With Linux running in Trustzone non-secure world, OP-TEE OS runs in
secure world, linux could use secure services provided by OP-TEE.
With TEE/OP-TEE options selected, use the bindings
in Documentation/devicetree/bindings/arm/firmware/linaro,optee-tz.txt
to let the driver probe work.

On i.MX6/7, now the bootflow is U-Boot->OP-TEE->Linux, OP-TEE will
automatically create that node.

This option was removed by "make savedefconfig" in
commit c5054a98 ("ARM: imx_v6_v7_defconfig: Select SMSC_PHY")

This happened because CONFIG_DEBUG_FS was implicitly selected by
CONFIG_TREE_RCU_TRACE which defaulted to true because CONFIG_RCU_TRACE
was enabled by default by commit 96151825 ("rcu: Enable RCU
tracepoints by default to aid in debugging")

Recently however CONFIG_RCU_TRACE was completely removed by
commit 6e74c237c410 ("rcu: Remove debugfs tracing")

The result is that imx_v6_v7_defconfig no longer includes DEBUG_FS on
linux-next since next-20170517. This is bad, DEBUG_FS is extremely
useful for kernel introspection and testing.

The imx6sl-evk board has a LAN8720A ethernet phy supported by SMSC_PHY.
Add this driver to the default imx config since the device is present on
one of the evaluation boards.

This used to work mostly fine with the generic phy driver until
commit 0878fff1 ("net: phy: Do not perform software reset for
Generic PHY"). The fact that soft reset is no longer performed
apparently causes RX to sometimes failes which can cause netboot to
timeout on DHCP. This is eventually retried and it works after link
up/down but can takes 90 seconds to reach the login prompt.

This was generated with "make savedefconfig" and it includes a few
additional minor cleanups.
