Make sure RPC PHY timing registers are configured before performing
bus access. These registers might have been left unconfigured or may
have been configured by a prior stage bootloader and leaving them
unconfigured or misconfigured would interfere with U-Boot operation.
Set PHYOFFSET1 DDRTMG field to 3 which enables DDR timing adjustment
when SPIDRE or DRDRE = 0 and set PHYOFFSET2 OCTTMG field to 4 which
makes the interface operate in Serial flash or HyperFlash mode.

Make sure DRDRENR register is configured before performing external
address space read. This register might have been configured by a
prior stage bootloader and leaving it unconfigured would interfere
with U-Boot operation. Since U-Boot RPC SPI driver does not support
DDR data transfer mode yet, set this register unconditionally to 0.

Instead of writing DRDMCR with 0 first and then overwriting DRDMCR again
in case any dummy bytes have to be sent out, write DRDMCR in every case
with the amount of dummy bytes that have to be sent out. In case no dummy
bytes have to be sent out, the value written into DRDMCR is zero, so no
dummy bytes are sent out. No functional change.

This patch adds 4-byte address mode support. Because traditional access
based on FIFO/shift register, it's complex to specify information like
opcode, address length, dummy bytes etc to flash. Replace the traditional
access by spi-mem layer which is essential to make 4-byte address mode
support possible.

[Marek: Squash S4 and V4H patches, fix brackets around STRTIM2]
Move strobe delay setting code into extra function and reflect the latest
setting in datasheet (R-Car Gen3 v2.20, R-Car V3U v0.50).
i.e. STRTIM[2:0] should be set to 110 (RCar M3-W) or 111 (Other products)
This is also a preparation for new R-Car Gen4 SoC which has 4-bits STRTIM

The compatible values used for device nodes representing Renesas Reduced
Pin Count Interfaces were based on preliminary versions of the Device
Tree Bindings.
Correct them in both DTSi files and drivers, to match the final DT
Bindings.
Note that there are no DT bindings for RPC-IF on RZ/A1 yet, hence the
most logical SoC-specific value is used, without specifying a
family-specific value.

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).
Rename some of the latter variables to end with 'plat' for consistency.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

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.
