pinctrl: renesas: Add support for 1.8V/2.5V I/O voltage levels
Currently, the Renesas pin control driver supports pins that can switch
their I/O voltage levels between either 1.8V and 3.3V, or between 2.5V
and 3.3V. However, some SoCs have pins that can switch between 1.8V and
2.5V.
Add support for this by replacing the separate SH_PFC_PIN_CFG_IO_VOLTAGE
capability and voltage level flags by a 2-bit field, to cover three
possible I/O voltage switching options.

dm: core: Report bootph-pre-ram/sram node as pre-reloc after relocation
Nodes with bootph-pre-sram/ram props are bound in multiple phases:
1. At TPL (bootph-pre-sram) or SPL (bootph-pre-ram) phase
2. At U-Boot proper pre-relocation phase
3. At U-Boot proper normal phase
However the binding and U-Boot Driver Model documentation indicate that
only nodes marked with bootph-all or bootph-some-ram should be bound in
the U-Boot proper pre-relocation phase.
Change ofnode_pre_reloc to report a node with bootph-pre-ram/sram prop
with a pre-reloc status only after U-Boot proper pre-relocation phase.
Also update the ofnode_pre_reloc documentation to closer reflect the
binding and driver model documentation.
This changes behavior of what nodes are bound in the U-Boot proper
pre-relocation phase. Change to bootph-all or add bootph-some-ram prop
to restore prior behavior.

dm: core: Allow marking driver model as dead
On x86 devices we use CAR (Cache-As-RAM) to hold the malloc() region in
SPL, since SDRAM is not set up yet. This means that driver model stores
its tables in this region.
When preparing to jump from SPL to U-Boot proper, we must disable CAR, so
that the CPU can uses the caches normally. This means that driver model
tables become inaccessible. From there until we jump to U-Boot proper, we
must avoid using driver model.
This is only a problem on boards which operate this way, for example
chromebook_link64
Add a flag to indicate that driver model is dead and should not be used.
It can be used in SPL to avoid hanging the machine.
