by means of the watchdog.

On iWave's boards iwg20d and iwg22d the only way to reboot the system is
by means of the watchdog.
This patch adds a restart handler to rwdt_ops, and also makes sure we
keep its priority to a medium level, in order to not override other more
effective handlers.

This commit documents the compatibility with R-Car Gen2 and RZ/G
devices by defining the generic compatible string "renesas,rcar-gen2-wdt".
Also, this patch expands the list of SoC-specific compatible strings to
include RZ/G and R-Car Gen2 devices.

commit adds "renesas,rcar-gen2-wdt" as compatible string for R-Car
Gen2 and RZ/G1, and since on those platforms the rwdt clock needs to be
always ON, when suspending to RAM we need to explicitly disable the
counting by clearing TME from RWTCSRA.

This patch allows for platform specific quirks as some of the SoC need
further customization for the watchdog to work properly, like for R-Car
Gen2 and for RZ/G.

This patch adds watchdog support by installing shmobile_boot_vector_gen2

When bringing up SMP or using CPU hotplug, the reset vector will jump
to shmobile_boot_fn instead.
Thank you All for your help.

o the amount of memory available.
Since shmobile_boot_vector has become bigger, "reg" property of nodes
compatible with "renesas,smp-sram" now need to be set to a value
greater or equal to "<0 0x60>".
