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.

add Xilinx_abort_fn to Xilinx_Spartan3_Slave_Serial_fns

Currently the hardware was left in an undefined state in case Spartan3
serial load failed. This patch adds Xilinx_abort_fn to give the board
a possibility to clean up in this case.

add block write function to spartan3 slave serial load

Using seperate function calls for each bit-bang of slave serial
load can be painfully slow. This patch adds the possibility to
supply a block write function that loads the complete block of
data in one call (like it can already be done with Altera FPGAs).
On an MCF5373L (240 MHz) loading an XC3S4000 this reduces the load
time from around 15 seconds to around 3 seconds

Big white-space cleanup.

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).

Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.
