The Linux AMBA bus framework probes the peripheral IDs when adding the
AMBA devices very early on the boot. Generally they are on APB bus and
just require APB clocks to be on even when most of the core logic of the
IP is powered down.

However on Juno, the entire debugsys domain needs to be ON to access
even the coresight components' CID/PID registers and hence broken by
design. Accessing those while debugsys power domain is off will lead to
the bridge stalling the transactions instead of returning the slave error.

Further, the AMBA framework can't deal with !CONFIG_PM_GENERIC_DOMAINS
case: it ignores the error and proceeds to access the device region.
It was suggested to always enable CONFIG_PM{,_GENERIC_DOMAINS} in order
to handle above explained scenario.

The ARMv8 Exynos family SoCs in Linux kernel are currently:
 - Exynos5433 (controlled by ARCH_EXYNOS),
 - Exynos7 (controlled by ARCH_EXYNOS7).

It duplicates Kconfig symbols unnecessarily, so consolidate them into
one ARCH_EXYNOS. Future SoCs could fall also under the ARCH_EXYNOS
symbol.

The commit should not bring any visible functional change.

All supported Renesas ARM64 SoCs have clock and power domains. To ensure
proper operation of on-SoC modules, module clocks must be ungated, and
power domains must be powered up when needed.

Currently the user can choose to build a kernel with power management
enabled or disabled:
  - If CONFIG_PM=y, power domains and/or module clocks are handled
    dynamically by Runtime PM and the generic power domain.
  - If CONFIG_PM=n, power domains are assumed to be powered up by reset
    state or by the boot loader, and module clocks are handled by the
    legacy clock domain on driver (un)bind.
    The latter is implemented using a platform bus notifier, which
    applies not only to all on-SoC devices, but to all platform devices
    present in the system.

To remove the dependency on implicit assumptions, and to get rid of the
peculiarities of the legacy clock domain, enable CONFIG_PM and
CONFIG_PM_GENERIC_DOMAINS unconditionally.
