Use the full driver model GPIO and serial drivers in SPL now that these are
supported. Since device tree is not available they will use platform data.

Remove the special SPL GPIO function as it is no longer needed.

This is all in one commit to maintain bisectability.

This is already set up in crt0.S. We don't need a new structure and don't
really want one in the 'data' section of the image, since it will be empty
and crt0.S's changes will be ignored.

As an interim measure, remove it only if CONFIG_DM is not defined. This
allows us to press ahead with driver model in SPL and allow the stragglers
to catch up.

This function has grown into something of a monster. Some boards are setting
up a console and DRAM here in SPL. This requires global_data which should be
set up in one place (crt0.S).

There is no need for SPL to use s_init() for anything since board_init_f()
is called immediately afterwards.

Since more than one board requires memory reservation
for the secure firmware, the reservation code can be
made in a common code.
Now, to reserve some part of the the last bank,
board config should define:
- CONFIG_TZSW_RESERVED_DRAM - len in bytes
- CONFIG_NR_DRAM_BANKS - number of memory banks

Each way of the system cache has 256 entries for PH1-Pro4 and older
SoCs, whereas 512 entries for PH1-Pro5 and newer SoCs.  The line
size is still 128 byte.  Thus, the way size is 32KB/64KB for old/new
SoCs.

To keep lowlevel_init SoC-independent, set BOOT_RAM_SIZE to the
constant value 32KB.  It is large enough for temporary RAM and
should work for all the SoCs of UniPhier family.

This function was intended for MN2WS0235 (what we call PH1-Pro4TV).
On that SoC, MPLL is already running on the power-on reset and it
makes sense to stop the PLL at early boot-up.
On the other hand, PH1-Pro4(R) does not have SC_MPLLOSCCTL register,
so this function has no point.
