ti: remove usage of DM_I2C_COMPAT and don't disable DM_I2C in SPL

DM_I2C_COMPAT is a compatibility layer that allows using the non-DM I2C
API when DM_I2C is used. The goal is to eventually remove DM_I2C_COMPAT
when all I2C "clients" have been migrated to use the DM API.
This a step in that direction for the TI based platforms.
Build tested with buildman:
buildman -dle am33xx ti omap3 omap4 omap5 davinci keystone

boot tested with:
am335x_evm, am335x_boneblack, am335x_boneblack_vboot (DM version),
am57xx_evm, dra7xx_evm, k2g_evm, am437x_evm

SPDX: Convert all of our single license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

ti: clocks: Fix do_enable_clocks() to accept NULL pointers as input parameters

Up till this commit passing NULL as input parameter was allowed, but not
handled properly.

When one passed NULL to one of this function parameters, the code was
executed causing data abort.

However, what is more interesting, the abort was not caught because of code
execution in HYP mode with masked CPSR A bit ("Imprecise Data Abort mask bit).
The TI's AM57xx SoC switch to HYP mode with A bit masked in lowlevel_init.S
due to SMC call. Such operation (by default) is performed in SoC ROM code.

The problem would pop up when one:
- Switch back to SVC mode after disabling LPAE support
- Somebody enables A bit (by executing cpsie a asm instruction)

and then the previously described exception would be caught.

ARM: OMAP4+: Add support for dynamically selecting OPPs

It can be expected that different paper spins of a SoC can have
different definitions for OPP and can have their own constraints
on the boot up OPP for each voltage rail. In order to have this
flexibility, add support for dynamically selecting the OPP voltage
based on the board to handle any such exceptions.
