This patch enables to use thermal-zone on DT if it was call as
"renesas,rcar-thermal-gen2".
Previous style is still supported by "renesas,rcar-thermal".

Above two function, always returns 0. Can it possible to handle error

This patch enables to use thermal-zone on r8a7790.
This thermal sensor can measure temperature from -40000 to 125000,
but over 117000 can be critical on this chip.
Thus, default critical temperature is now set as 115000 (this driver
is using 5000 steps) (Current critical temperature is using it as
90000, but there is no big reason about it)
And it doesn't check thermal zone periodically (same as current
behavior). You can exchange it by modifing polling-delay[-passive]
property.
You can set trip temp if your kernel has CONFIG_THERMAL_WRITABLE_TRIPS,
but you need to take care to use it, since it will call
orderly_poweroff() it it reached to the value.

I have marked this and the following shmobile patch as deffered
pending acceptance of the driver changes (earlier in the patchset).
Please repost the shmobile patches once that has occurred.
