To clean up reset handling for socfpga gen5, port the DDR driver to DM
using UCLASS_RAM and implement proper reset handling.
This gets us rid of one ad-hoc call to socfpga_per_reset().
The gen5 driver is implemented in 2 distinct files. One of it (containing
the calibration training) is not touched much and is kept at using
hard coded addresses since the code grows even more otherwise.
SPL is changed from calling hard into the DDR driver code to just
probing UCLASS_RESET and UCLASS_RAM. It is happy after finding a RAM
driver after that.

The 'dwmac_socfpga' ETH driver can now get the MACs out of reset
via the socfpga reset driver and can set PHY mode via syscon.
This means we can now remove the ad-hoc code to do this from
arch/arm/mach-socfpga.

The Arria10 SPL is a complete mess of calls to functions which are
called in the wrong context and it is surprise it works at all. This
patch tries to clean that mess up by shuffling the function calls
around and moving the calls into the correct context. Due to the
delicate nature of the reordering, this is done in one huge patch.
The following changes happen in this patch:
- Security policy init and NIC301 happens first in board_init_f()
- The clock init happens very early in board_init_f() in SPL only
- arch_early_init_r() only registers the FPGA, just like on Gen5
- arch_early_init_r() is never called from any _f() function
- Dedicated FPGA pins are inited in board_init_f() as on Gen5

The Arria10 uses slightly different boot image header than the Gen5 SoCs,
in particular the header itself contains an offset from the start of the
header to which the Arria10 jumps. This offset must not be negative, yet
the header is placed at offset 0x40 of the bootable binary. Therefore, to
jump into U-Boot, add a trampoline just past the Arria10 boot header and
point to this trampoline at fixed offset from the header generated using
the mkimage -T socfpgaimage_v1 . Note that it is not needed to jump back
to offset 0x0 of the image, it is possible to jump directly at the reset
label and save processing two instructions.

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 mpuclk register in the Altera group of the clock manager
divides the mpu_clk that is generated from the C0 output of the main
pll.
Without this patch, the default value of the register is 1, so the mpuclk
will always get divided by 2 if the correct value is not set. For example,
on the Arria5 socdk board, the MPU clock is only 525 MHz, and it should be
1.05 GHz.
