driver/ddr/fsl: Fix driver to support empty first slot

CS0 was not allowed to be empty by u-boot driver in the past to simplify
the driver. This may be inconvenient for some debugging. This patch lifts
the restrictions. Controller interleaving still requires CS0 populated.

drivers/ddr/fsl: Update DDR driver for DDR4

Add/update registers for DDR4, including DQ mappings. Allow raw timing
method used for all controllers. Update mode_9 register to 0x500 for
improved stability. Check DDR controller version number individually
in case a SoC has multiple DDR controllers of different versions.
Increase read-write turnaround for DDR4 high speeds.

MPC8541/MPC8555: Enable SS_EN in DDR_SDRAM_CLK_CNLT register

According to the MPC8555/MPC8541 reference manual the SS_EN (source
synchronous enable) bit in the DDR_SDRAM_CLK_CNLT register must be set
during initialization.

>From section 9.4.1.8 of that manual:

Source synchronous enable. This bit field must be set during
initialization. See Section 9.6.1, "DDR SDRAM Initialization
Sequence," details.

0 - Reserved
1 - The address and command are sent to the DDR SDRAMs source
synchronously.

In addition, Freescale application note AN2805 is also very clear that
this bit must be set.

This patch reverts a change introduced by commit
457caecdbca3df21a93abff19eab12dbc61b7897.

Testing Done:

Compiled targets CONFIG_TARGET_MPC8555CDS and CONFIG_TARGET_MPC8541CDS
and inspected the generated assembly code to verify the SS_EN bit was being
set. There is one extra instruction emitted:

fff9b774: 65 29 80 00 oris r9,r9,32768

Compiled the CONFIG_TARGET_MPC8548CDS target and verified that no
additional instructions were emitted related to this patch.

Booted an image on a MPC8541 based board successfully.

Increase write-to-write and read-to-read turnaround time for two-slot DDR

have this additional turnaround time. A recent test on two single-rank
DIMMs shows the shorter additional turnaround time is also needed.

linux/kernel.h: sync min, max, min3, max3 macros with Linux

U-Boot has never cared about the type when we get max/min of two
values, but Linux Kernel does. This commit gets min, max, min3, max3
macros synced with the kernel introducing type checks.

Many of references of those macros must be fixed to suppress warnings.
We have two options:
- Use min, max, min3, max3 only when the arguments have the same type
(or add casts to the arguments)
- Use min_t/max_t instead with the appropriate type for the first
argument

driver/ddr/fsl: Add support of overriding chip select write leveling

JEDEC spec allows DRAM vendors to use prime DQ for write leveling. This
is not an issue unless some DQ pins are not connected. If a platform uses
regular DIMMs but with reduced DDR ECC pins, the prime DQ may end up on
those floating pins for the second rank. The workaround is to use a known
good chip select for this purpose.
