dts: imx8m{m,n,p,q}: Make optee packaging optional

binman can omit packaging an optional blob when it is missing.
This allows us to not bother with config options.
The core challenge is the interaction between tf-a and OP-TEE where
U-Boot/binman does not know whether tf-a was built with SPD=opteed or
without. This is important because tf-a might jump into the void when no
optee_os is present, leading to boot failure. Thus by marking it
optional, user is prompted to recheck (due to the warning message)
whether they really have the right combination of tf-a and optee.

Due to a bug in binman, we had to guard binman tee.bin with OPTEE config
as builds would error when tee.bin was not present in path; Even though
optee_os was marked as optional in the binman tree. Since the bug has
been resolved in
commit d4f61eae2ab7 ("Merge patch series "Fix handling of optional blobs in binman"")
we can mark it optional again without getting build errors.

Note that after this commit a warning will be printed when optee is not
present for a binman build.

Image 'image' is missing optional external blobs but is still functional: tee-os

net: phy: Support overriding Auto Negotiation timeout with env variable

The Auto Negotiation procedure between two Ethernet PHYs consists of
determining the best commonly supported parameters among Speed,
Duplex Mode and Flow Control.

The time taken for this procedure is not only dependent on the local
PHY used, but also on the link-partner PHY.

While a timeout can be specified in the form of a "CONFIG" on the basis
of the local PHY present on the device, since the timeout also depends
on the link-partner PHY, it might be necessary to modify the timeout.

To avoid rebuilding the bootloader for a given device, just because it
may be connected to various link-partner PHYs, each with a different
timeout, introduce an environment variable named "phy_aneg_timeout" and
override "CONFIG_PHY_ANEG_TIMEOUT" with "phy_aneg_timeout".
