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.

Commit a85362fb3e refactored the code
but the register read ended up in the wrong if branch.
Currently, the else branch checks a variable which is always 0.

The TWL6030 power driver is only built when CONFIG_TWL6030_POWER is selected,
thus there is no reason to wrap the code with ifdef.

When booting from USB, the bootrom sets the VUSB_IN_PMID bit of the MISC2
register of the TWL6030. However, U-Boot sets the VUSB_IN_VSYS bit to enable
VBUS input. As both bits are contradictory, enabling both disables the input,
according to the TWL6030 TRM.
Thus, we need to clear the VUSB_IN_PMID bit in case of an USB boot (which could
just as well be a memory boot after USB timed out).

Not every device has multiple MMC slots available, so it makes sense to enable
only the required LDOs for the available slots. Generic code in omap_hsmmc will
enable both VMMC and VAUX1, in doubt.

This enables the VAUX1 supply, used for eMMC power in standard configurations.
Its voltage is determined by the value of the BOOT2 pin of the TWL6030.
Note that the TWL6030 might already have enabled this regulator at startup
(depending on the value of the BOOT3 pin of the TWL6030), according to the
TWL6030 datasheet.

This makes the twl6030 mmc and usb-related power registers and values
definitions more explicit and clear and adds prefixes to them.

The data struct is used to support different
PMIC chip types. It contains the chip type and
the data (e.g. registers addresses, adc multiplier)
which is different for twl6030 and twl6032.
Replaced some hardcoded values with the
structure vars.

twl6030_i2c_[read|write]_u8 can be used else where to access
multi-function device such as twl6030, so move the register access
functions to the common twl6030.h header file.
