ssb: relax SSB_EMBEDDED dependencies

This is a kconfig warning in a randconfig when CONFIG_PCI is not set:

WARNING: unmet direct dependencies detected for SSB_EMBEDDED
Depends on [n]: SSB [=y] && SSB_DRIVER_MIPS [=y] && SSB_PCICORE_HOSTMODE [=n]
Selected by [y]:
- BCM47XX_SSB [=y] && BCM47XX [=y]

This is caused by arch/mips/bcm47xx/Kconfig's symbol BCM47XX_SSB
selecting SSB_EMBEDDED when CONFIG_PCI is not set.

This warning can be prevented by altering SSB_EMBEDDED to allow for
PCI=n or the former SSB_PCICORE_HOSTMODE.

Above commit added "SSB = y" dependency to the wrong symbol
SSB_DRIVER_PCICORE_POSSIBLE and prevented SSB_DRIVER_PCICORE from being
selected when needed. PCI core driver for core running in clienthost
mode is important for bus initialization. It's perfectly valid scenario
to have ssb built as module and use it with buses on PCI cards.

This fixes regression that affected all *module* users with PCI cards.

ssb: Disable PCI host for PCI_DRIVERS_GENERIC

Since commit d41e6858ba58 ("MIPS: Kconfig: Set default MIPS system type
as generic") changed the default MIPS platform to the "generic"
platform, which uses PCI_DRIVERS_GENERIC instead of PCI_DRIVERS_LEGACY,
various files in drivers/ssb/ have failed to build.

This is particularly due to the existence of struct pci_controller being
dependent on PCI_DRIVERS_LEGACY since commit c5611df96804 ("MIPS: PCI:
Introduce CONFIG_PCI_DRIVERS_LEGACY"), so add that dependency to Kconfig
to prevent these files being built for the "generic" platform including
all{yes,mod}config builds.

There is code in ssb fetching "invariants" that is basically a set of
board specific data. Every host requires its own implementation of
reading function. In ssb we have support for PCI, PCMCIA & SDIO.
For some (historical?) reason code reading "invariants" for SoC was
placed in arch code and provided by a callback. This is not needed
nowadays, so lets move that into ssb. This way we keep all "invariants"
functions in a single module making code cleaner.

kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.
