Drop legacy platform data omap variants for v5.4

We can now drop more platform data in favor of dts data for most
devices like cpsw, gpio, i2c, mmc, uart and watchdog.

In general we can do this by dropping legacy "ti,hwmods" custom dts
property, and the platform data assuming the related dts data is correct.
This is best done as single patch as otherwise we'd have to revert two
patches in case of any unexpected issues, and we're just removing data.

Fro cpsw, before we can do this, we need to configure the cpsw mdio clocks
properly in dts though in the first patch. For omap4 i2c, we've already
dropped the platform data earlier, but have been still allocting it
dynamically based on the dts data based on the "ti,hwmods" property, but
that is no longer needed. For d2d, we are missing the dts data, so we
first add it and then drop the platform data.

For dra7, we drop platform data and "ti,hwmods" for mcasp and mcspi.
We've already dropped platform data earlier for gpio, i2c, mmc, and
uart so we just need to drop "ti,hwmods" property for those.

Note that this branch is based on earlier ti-sysc-fixes branch.
