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.

The reference implementation of the PCI initialization code almost
everywhere contain this fragile loop of "a few usecs", and its
use of volatile variables to delay a number of bus cycles is indeed
uncertain.
Reading the manual "Integrator/AP Users Guide", page 5-15 it is
clearly stated:
"Wait until 230ms after the end of the reset period before
accessing V360EPC internal registers. The V360EPC supports the
use of a serial configuration PROM and the software must wait for
the device to detect the absence of this PROM before accessing any
registers. The required delay is a function of the PCI Clock, but
at the lower frequency (25MHz) is 230ms".
So let's simply wait 230ms per the spec.
This solves the compilation error that looked like this:
pci.c: In function ‘pci_init_board’:
pci.c:286:18: warning: variable ‘j’ set but not used

The PCI support for the Integrator AP has apparently never
been finished and I strongly suspect that it has never worked,
so let's fix it. This is a list of the more or less
un-splittable changes done in this driver rewrite:
- Replace the register definitions stashed into the config
file (!) with a copy if the register file from the Linux
kernels arch/arm/include/asm/hardware/pci_v3.h
- Delete the unreadable gigantic macros that perform the
config accesses and replace them with copyedited code from
Linux arch/arm/mach-integrator/pci_v3.c
- Rewrite the rest of the setup code to use the
v3_[read|write][lwb]() accessors.
- Enable PCI by default in the AP board configuration.
- Fix checkpatch warnings and make code more conformant.

actually the timer init use the interrupt_init as init callback
which make the interrupt and timer implementation difficult to follow
so now rename it as int timer_init(void) and use interrupt_init for interrupt
btw also remane the corresponding file to the functionnality implemented
as ixp arch implement two timer - one based on interrupt - so all the timer
related code is moved to timer.c

The PCI_REGION_MEMORY and PCI_REGION_MEM are a bit to similar and
can be confusing when reading the code.
Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY to clarify its used
for system memory mapping purposes.

Correct addessing errors in platform files.
Split off common core module data from Integrator header files to
include/armcoremodule.h.
