ARM: uniphier: enable PSCI sysreset for uniphier_v8_defconfig

This configuration is supposed to be used with ARM Trusted Firmware,
so the SYSTEM_RESET is implemented in BL31. Invoke PSCI instead of
U-Boot's own reset code because we need to coordinate with SCP
(System Control Processor) for the system-level power management.

The spl_boot_mode() is unrelated to the other code in this file.
Besides, this function is only called from common/spl/spl_mmc.c,

ARM: uniphier: simplify SoC ID get function

Currently, uniphier_get_soc_type() converts the SoC ID (this is

conversion in the first place. Using the SoC ID from the register
as-is a straightforward way.

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.

[2] board_early_init_f()
[3] board_init()
[4] board_early_init_r()
[5] board_late_init()

The serial console is not ready at the point of [2], so we want to
avoid using [2] from the view point of debuggability. Fortunately,
all of the initialization in [2] can be delayed until [3]. I see no
good reason to split into [3] and [4]. So, merge [2] through [4].

This commit supports it on all the UniPhier SoCs (including the new
