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.

ARM: am33xx: Inhibit re-initialization of DDR during RTC-only

This inhibits the re-inititialization of DDR during an RTC-only resume. If
this is not done, an L3 NOC error is produced as the DDR gets accessed
before the re-init has time to complete. Tested on AM437x GP EVM.

arm: omap: Unify get_device_type() function

Refactor OMAP3/4/5 code so that we have only one get_device_type()
function for all platforms.

Details:
- Add ctrl variable for AM33xx and OMAP3 platforms (like it's done for
OMAP4/5), so we can obtain status register in common way
- For now ctrl structure for AM33xx/OMAP3 contains only status register
address
- Run hw_data_init() in order to assign ctrl to proper structure
- Remove DEVICE_MASK and DEVICE_GP definitions as they are not used
(DEVICE_TYPE_MASK and GP_DEVICE are used instead)
- Guard structs in omap_common.h with #ifdefs, because otherwise
including omap_common.h on non-omap4/5 board files breaks compilation

Buildman script was run for all OMAP boards. Result output:
arm: (for 38/616 boards)
all +352.5
bss -1.4
data +3.5
rodata +300.0
spl/u-boot-spl:all +284.7
spl/u-boot-spl:data +2.2
spl/u-boot-spl:rodata +252.0
spl/u-boot-spl:text +30.5
text +50.4
(no errors to report)

Tested on AM57x EVM and BeagleBoard xM.

arm: am33xx: Fix MPU opp selection

Update MPU frequencies and voltages as per the latest
DM[1] dated: OCT 2011 Revised APRIL 2016, Section 5.4.
Below is the consolidated data:

MPU values for PG 2.0 and later(Package ZCZ and ZCE):

| | ZCZ | ZCE |
|-------------------------------------------------------|
| | VDD[V] | ARM [MHz] | VDD[V] | ARM [MHz] |

|-------|----------|------------|----------|------------|
| OPP50 | 0.95 | 300 | 0.95 | 300 |
-------------------------------------------------------

There is no eFuse blown on PG1.0 Silicons due to which there is
no way to detect the maximum frequencies supported. So default
to OPP100 for which both frequency and voltages are common on both
the packages.
