fix(rcar5): prevent boot CPU hot unplug

The boot CPU runs both TFA and later also Trusted OS, which is
UP and can not be migrated to another CPU. Report MIGRATE_INFO_TYPE
"Uniprocessor (UP) not migrate capable 1" to the OS, so any attempts
at CPU_OFF and MIGRATE of the boot CPU would be DENIED. This has an
effect also e.g. on the Linux kernel, where it prevents stopping
boot CPU (CPU0) using CPU hotplug, which must not be allowed,
as it would interfere with the Trusted OS.

feat(rcar): rewrite console_renesas_register() in C

Replace assembler implementation of console_renesas_register() with
matching C implementation. Since it is now easily possible to pass
flags into console_renesas_register() and then onward to the console
initialization, adjust the signature of console_renesas_register()
and include the flags in it. Adjust both rcar_console_boot_init()
and rcar_console_runtime_init() to call console_renesas_register()
with its new combined set of parameters and drop console_set_scope()
invocation which is no longer needed, because the flags are passed
directly into console_renesas_register().

Drop console_renesas_flush() which is always a noop. Drop return
value from console_renesas_init() which is always 1.

refactor(rcar): rename console_rcar_ to console_renesas_ prefix for Renesas platform

refactor(rcar): rename console_rcar_ to console_renesas_ prefix for Renesas platform

Rename console_rcar_ to console_renesas_ prefix for SCIF-based console
driver to make it reusable by other Renesas platforms.

Due to the above renaming, function console_renesas_register is duplicated
in both scif.h and console.h, so it should be removed from scif.h

fix(rcar5): enable missing FEAT_AMUv1p1 on R-Car Gen5 to fix the build

Since commit 6edbd2d6a8ae ("fix(cpufeat): require FEAT_AMUv1p1 to
enable the auxiliary counters") the ENABLE_AMU_AUXILIARY_COUNTERS
requires ENABLE_FEAT_AMUv1p1 to be enabled as well. Enable missing
ENABLE_FEAT_AMUv1p1 to fix the build, which was broken because the
R-Car Gen5 and FEAT_AMUv1p1 commits landed in reverse order.

(Cortex-A720AE, 8 clusters x 4 cores)
- Platform-specific PSCI power management and topology
- SCMI-based power domain and system power management
- GICv4/Fainlight-AE interrupt controller initialization and support
- Trusted SRAM, shared memory, and crash log region setup
- SCIF console support
- Stack protector implementation for enhanced security
- Platform-specific linker script and build integration
- Various helper and initialization routines for MMU, GIC, and SCMI
- Platform-specific mailbox and boot flow handling
- Basic suspend implementation via SCP-FW
- AMU counters, SVE, PAUTH accessible to EL1
