This patch makes the on-board RTC work on the socfpga_socrates board.
This rtc is present on the board, but it does not work (fails with a
timeout).
This patch adds a weak pull-up on the I2C0-SCL pin connected to the m41t82
RTC on this board. While the SDA line has a pull-up on the pcb, the pull-up
on the SCL line seems to be missing. To work around this, enable the
weak-pull-up feature on this pin.
After applying this patch, the rtc timeout is gone and the 'date' command
can access the rtc chip.

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.

Adding new handoff for SDRAM ctrcfg.extratime1 which is
required for stable LPDDR2 operation. Since the board is
using DDR3, the handoff is set to default value 0.

This board was constantly parasiting on the CV SoCDK, so split it
into it's own separate directory. Moreover, the board config was
missing important bits, like simple-bus support in SPL, the DRAM
configuration was incorrect and the DTS was also missing the pre
reloc bits.
