platform: tegra: Import tegra_prod and wdt-recovery drivers

This changes imports tegra_prod and wdt-recovery drivers from k4.4.
It squashes below three original commits to make the change neat as
the original commits contained many other drivers as well:
  commit c5c90b82ec25 ("drivers: platform: tegra: Add miscellaneous
  			platform specific drivers")
  commit 000acb1cd376 ("platform: tegra: add missing headers and
  			build fixes")
  commit 0b95640a2a30 ("include/linux: add missing tegra headers")
  commit c413070a1e21 ("platform: tegra: Get rid of mach/irq.h
  		  	include")

Bug 200416207
