00aa453ebf ARM: uniphier: remove sLD3 SoC support
This SoC is too old.  It is difficult to maintain any longer.

ee8d037ce7 ARM: uniphier: remove SPL support for ARMv8 SoCs
It has been a while since ARM Trusted Firmware supported UniPhier SoC
family.  U-Boot SPL was intended as a temporary loader that runs in
secure world.  It is a maintenance headache to support two different
boot mechanisms.  Secure firmware is realm of ARM Trusted Firmware
and now U-Boot only serves as a non-secure boot loader for UniPhier
ARMv8 SoCs.

14bb7a4e37 ARM: uniphier: revive accidentally removed dcache_disable()
Commit a8e6300d48 ("ARM: uniphier: refactor spl_init_board()")
accidentally dropped dcache_disable() call.  Since then, the SPL of
LD11 and LD20 failed to load U-Boot proper.

ee8ef5afa8 ARM: uniphier: add macro to generate SoC data look-up function
There are similar functions that look up SoC data by the SoC ID.
The new macro UNIPHIER_DEFINE_SOCDATA_FUNC will be helpful to
avoid the code duplication.

e27d6c7d32 ARM: uniphier: simplify SoC ID get function
Currently, uniphier_get_soc_type() converts the SoC ID (this is
read from the revision register) to an enum symbol to use it for SoC
identification.  Come to think of it, there is no need for the
conversion in the first place.  Using the SoC ID from the register
as-is a straightforward way.

26b09c022a ARM: uniphier: move SBC and Support Card init code to U-Boot proper
Initialize SBC and Support Card in U-Boot proper instead of SPL.

We may run different firmware (ex. ARM Trusted Firmware) before
U-Boot, and basic SoC initialization may be done there.  In that
case, SPL may not be used.

The motivation for preparing SBC and Support Card in SPL was to use
LED for early debugging, but this is not mandatory to boot SoCs.
With this commit, LED will be unavailable in SPL, but we can use a
debug serial instead.  So, this change will not be a big deal.

a8e6300d48 ARM: uniphier: refactor spl_init_board()
Merge init-*.c into a single file using a table of callbacks because
the initialization flow is almost common among SoCs.
